Still looking for Clifford, Marion is asked to give evidence against Yamauchi. Joss meets up with Stephen Wentworth, an old friend of Monica's (the women she spent most of the series looking for), who has opened a center to help the natives. Kate learns Tom is in hospital and has TB. Marion returns home to her house, and finds it in perfect order, having been taken over by the Japs for most of the war. Dorothy's house, meanwhile, has been trashed by the locals. Stephen wants Joss to help him at the center. Dorothy and Maggie are befriended by Jake Haulter, who seems to have an uncanny (and probably black-market) knack for procuring things. Marion gets an urgent message to go back to the hotel, and fears the worst about Clifford.

Marion is reunited with Clifford, who is at the hotel waiting for her, and tells her Ben is okay. Clifford reveals he is in charge of leading the hunt for war criminals, and intends to start by tracking down and hanging Yamauchi. Bea, still furious about Yamauchi withholding medicines, agrees to testify against him. She also learns that she is slowly going blind. Meanwhile, Marion is annoyed as Clifford tries to wrap her up in cotton wool and keep her away from the others. More internees arrive at Raffles and reveal that Nellie died just a few months from the end of the war. Mrs Van Meyer gossips about Dorothy's involvement with Shinya. Some of the new arrivals at Raffles bully Dorothy for being a collaborator; they chase her down a corridor and she runs right into Sister Ulrica.

Sister Ulrica catches up with the other women and counsels Dorothy, who finds out her mother is dead and leaves to go back to England. Clifford and Marion have drifted apart badly: he doesn't want to hear about the camps, which is all she wants to talk about. Mrs Van Meyer learns Mr Van Meyer is presumed dead and she cannot get to any of his money, leaving her penniless. Marion is furious at Clifford for reading her diary and he realises the other internees know her better now than he ever could. Jake offers Maggie a place to stay. Bea tells Marion that she is going blind and is conned into helping out at the center by Joss. Jake gets Joss free medicine for the center.

The women start being questioned by the military to give evidence against Yamauchi and co for war crimes: Bea flips out, Mrs Van Meyer tells lots of lies and Maggie gives emotional testimony about Blanche's death. Joss is arrested by the police for being with Christina's uncle. Clifford tells Marion that Yamauchi is in Singapore. Stephen announces he is staying in Singapore to run a center; he wants Joss to come back and help him run it. Marion refuses to testify against Yamauchi; so do Christina, who goes to visit him, and Sister Ulrica. Everyone begins doubting things they said and did in the camps, including Sister Ulrica and Mrs Van Meyer.

Kate is distraught when Tom dies and seeks comfort from Sister Ulrica, who comes to the funeral even though Tom was a protestant. Kate also decides she definitely wants to become a doctor. Marion visits Yamauci in prison, with Jake's help in pulling strings. He tells her he knew about her diary and let Christina steal the paper for it. She apologises that it will be used to prosecute him. He tells her that he would rather die than go to prison - it is the more honourable way out. Bea has to explain the facts of life to Alice after a boy gets a little too friendly with her. Maggie realises that she is pregnant. Clifford and Marion fight over her visiting Yamauchi and she says she doesn't know if they have a future together.

The women all prepare to go home, and say goodbye to Alice as she sets sail for England. The Jeffersons' marriage is clearly in trouble as Clifford sees how much Marion has changed since she has been in the camps. Jake tells Maggie that he knows she is pregnant and she is torn over what to do about the baby. She eventually decides to go back to England as well. Christina decides to stay in Singapore and become a teacher. Mrs Van Meyer learns, to her horror, that Mr Van Meyer is still alive and tells Marion she doesn't know what to do now, that she never loved him. Joss feels under the weather and is admitted to hospital after being mugged.

The women all prepare to leave Singapore to go back home, agreeing to have a reunion at Raffles in 1950, exactly five years after they separate. Joss dies in hospital. Bea agrees to stay on in Singapore and help Stephen run the centre. Sister Ulrica goes to visit Yamauchi, who tells her he knows he will be hanged. Maggie agrees to go and stay with Dorothy in London. Everyone reminisces about absent friends: Joss, Rose, Blanche and all the others who died, and then say their goodbyes as they all go their separate ways. Marion realises the experience is finally over as she sails for home.

Five years after the end of the war, a chance encounter between Marion and Dorothy prompts Marion to try and organise a reunion at Raffles for them and their fellow ex-internees. In Singapore, they are reunited with the rest of their group - Bea, Kate, Christina, Maggie, Alice and the remarried Mrs Van Meyer, now Mrs Forster-Brown. They reminisce about the past and look forward to the future.
