At the end of the Second World War, a British intelligence officer must persuade a kidnapped German scientist to work with the British RAF to develop the jet engine.

Summary
It is the end of the Second World War and Lotte and her father Dieter, a recently captured German scientist, arrive in England. Captain Callum Ferguson, an intelligence officer, is assigned the task of courting Dieter into working with the British RAF to develop the jet engine. With the emerging Cold War, it is crucial for British national security that cutting-edge technology is made available to the armed forces as quickly as possible.

Meanwhile, Kathy Griffiths from the War Crimes Unit is looking to bring war criminals who escaped prosecution to justice. As Lotte navigates the strange corridors of the bomb-damaged London hotel where they are staying under the British government's watchful eye, Callum must win over the trust of her father.

Plot
It's the year 1946. German engineer Dieter Koehler and his daughter Lotte Koehler along with other German captives are seized from Germany and brought to England by the British government. Dieter is being interrogated and he angrily states that he's not going to change his mind no matter what. He and Lotte are then taken somewhere else. Lotte accidentally drops her toy donkey and has a hard time retrieving it due to a crowd; a stranger gives the donkey back to her. She finally catches up her father.

The next morning Lotte is woken up by a vehicle noise in some room. Captain Callum Ferguson greets her and tells her that there's no need to be afraid and he's here to take her to breakfast. He then tries to talk to her in German. Lotte, who doesn't know English well, says "Prison?" to which he replies that she's not in prison. Captain Ferguson later explains their location to her and says that she'll be able to meet her father in a couple of hours. He's then informed that Brigadier Wainwright wants to see him.

Brigadier has ordered to burn some files, which catches Callum's attention. There's a man outside, who watches the burning process. Brigadier assigns Captain the task of "babysitting" Dieter (who is a brilliant jet engineer) and making him start working for the British government. He reveals that they snatched him and Lotte out of the bed in the midnight. Because of that, Dieter is irritated and doesn't want to cooperate with the British government. Callum tells him that he's being demobbed in six weeks, but Brigadier says that it will only take six days. Callum eventually agrees.

Lotte finally reunites with her father and they are taken to the Connington Hotel.

Captain Ferguson arrives at the hotel, where he's greeted by Ringwood. He shows him around the hotel and explains bits and bobs about it. Ringwood takes him to his bedroom, and then to the secret floor, where they secretly listen to the people who they are interested in. Callum notices files, that as Ringwood explains, are the interviews from Germany. He then listens to Dieter, who's speaking to his daughter in German. Callum explains to Ringwood that it's very important Dieter to design the jet engine for the British government in order to win the war. After that they go to Dieter's room. He greets them unpleasantly and asks them if they are the jailors. Callum denies it and tries to be friendly. He asks Dieter if he and Lotte can have dinner with him. He refuses and says that apart from everything they have nothing to wear. Callum promises them that Ringwood will go shopping for Lotte.

Back at the T-Force department, Brigadier notices the War Crimes Unit investigator Kathy Griffiths, which annoys him. Brigadier is going to the appointment and Miss Griffiths follows him. She first mentions the fact that they are getting rid of some paperwork, to which he replies that it's just a housekeeping and the files aren't important. Then she asks him about the names of the war criminals that WCU sent him, but Brigadier says that he didn't get any. Miss Griffiths knows that he's not telling the truth and tries to reassure him. Brigadier says that getting information from these people is very important for the government. She then asks him to use the files they have in order to help WCU track down another names that they weren't familiar with. Brigadier tells her to send the list again and promises they'll do their best to be of help. He then goes to the appointment. Miss Griffiths' expression shows her disbelief.

Callum and Ringwood take Dieter and Lotte to dinner, but they refuse to eat. Dieter says that the shock of suddenly being seized in one's home and brought here doesn't make one hungry. He tells him that people were screaming at them and guns were being pointed to their faces in the middle of the night; the British were taking absolutely everybody, including an old couple, who worked for the drinks company. Callum says that capturing the old couple was an obvious mistake but this kind of actions are necessary for the time being. After that Dieter says that Lotte loves the cabbage with garlic, onions and butter which her mother, Mrs. Koehler and after her death their cook used to make for her. Callum calls the waiter and orders a special cabbage portion, but he says that they can't make it. Annoyed Callum excuses himself and goes to the Maître D'. He manages to convince him to cook Austrian cabbage, which they don't usually do. Lotte finally eats the dinner. Harold Lindsay-Jones, who was having the dinner as well, saw everything and asked the waiter if he could get the same cabbage.

After the dinner, Callum tells Ringwood to put Dieter and Lotte to bed and make sure there's always someone outside their door. As they speak, the loud drumming can be heard. Callum follows the noise and ends up in a basement ballroom, where he sees the drummers practicing and meets an American singer Eva, who tells him that they are preparing for the grand opening, to which he replies that he wasn't familiar with. He promises her that he'll attend the ceremony. Eva then tells him that she's heard Army's using the hotel and asks if he was from the Army. He doesn't answer and just smiles, implying that he is.

Callum is walking down the hall when he hears Harold's voice. He congratulates him for getting the special cabbage and says that he wasn't so lucky and next time he'll try storming the kitchen himself. He then remembers what the basement ballroom was like before the war. Callum excuses and says he has to go.

Callum goes to The Secret Floor and asks Ringwood for some files to read, when all of a sudden a phone rings. It's Alex calling for Callum. He insists on meeting the next day. As they speak, Lotte starts to cry. Callum hangs up and listens to her through the headphones. He realizes that she says she wants to go home.

A woman knocks on the door next to Callum's room and a man lets her in after saying "I thought maybe you weren't coming." Callum is in his room reading files. Shortly after he hears moaning and smiles. After a while, he still isn't asleep and all of a sudden hears someone stumble on plates and decides to check where the sound is coming from. As he opens the door, Julia notices him and apologizes. She then says that he doesn't seem to be awaken by the noise, to which Callum replies that he was awake as he was working. Julia asks him whether he was thinking about her that she was working too. Callum denies it. Julia thanks him and leaves.

In the morning, Ringwood tells Callum that Dieter and Lotte refuse to eat once again. Callum takes them to W. Hargreaves' shop, where he buys toffee apple for Lotte. At this point he notices a woman watching them from the outside and tells Ringwood to take care of the father and daughter from know. He then approaches the woman, Miss Griffiths, who introduces herself to him and asks him if he's from the T-Force. Callum doesn't deny it. Miss Griffiths asks him "politely" to help her get the records. Callum apologizes for having to go to see his friend and his wife and tells Miss Griffiths to come to the hotel the next day at four o'clock and they can have a meeting.

Callum goes to the restaurant where he meets his pal Alex and his wife Rachel, who have recently returned from the US. Rachel says that Alex told her a lot about Callum and she was looking forward to meet him. She hopes that they'll chat for a while, but Callum apologizes and says he has to go. Rachel manages to convince him to stay and eat an English ice-cream, which she was very curious to taste. Alex jokingly says that they are endangering their health by eating it. Callum reveals to them that he's trying to "make a German engineer happier". He also mention the grand opening and Rachel says that she and Alex will certainly attend, even though they're supposed to have a date night that day.

Callum returns to the hotel only to find out that Lotte is still refusing to eat and she's crying, which bothers other guests who are having the dinner. Dieter tells him that he couldn't make her sit still. Callum manages to calm her down by pointing out that the man sitting near them might be keeping an eye on him the same way he keeps an eye on her. He then approaches the man, who introduces his ward, Lucy to Callum and tells him that his name is Harold Lindsay-Jones. Callum apologizes to them for any disturbance. Harold jokingly says: ''Yesterday she was a little angel in that coat that was too big for her. One night in this hotel and look what happens.''

The next day Miss Clarkson, who is the chairwoman of WCU, tells Miss Griffiths that they are in a tight spot; two more people are leaving them and the government officials are trying to move them into a smaller office. She says that they don't have much time before the government starts winding them down. Miss Clarkson then asks Miss Griffiths if she had any luck with T-Force, to which she replies that not in Enfield, but she has a lead in the Connington and expects to find out the information they need.

Everyone on the secret floor is creeped out as they hear Lotte crying loudly through the speakers. One of the agents, who does eavesdropping using the devices, says that listening to this is horrible. Ringwood suggest calling a doctor but Callum says it's not necessary.

Callum storms to the Koehlers' room and bangs on the door with rage. Dieter, who's not aware of the fact that his room is being listened, opens the door and angrily asks Callum if the wardens standing by their door told him what was happening. Callum says yes. Lotte is sitting on the bed and crying loudly. Dieter says that this can't go on, his daughter needs to go back in Germany and that's the only option. Lotte begs him to let her go home as she cries.

Callum tries to decide what to do next, and notes that he's not having the greatest success giving them the time of their life. He then approaches Lotte and tells her to get out of the bed. He knocks out the drawer and pulls out the microphone that was attached to the back of the drawer.
