Ulrica is made leader of the Dutch internees. The older women worry when the younger women are unexpectly removed from the camp, but it turns out they're being used for labor crews. Dorothy smuggles milk into the camp for her baby, but is caught, and everyone is punished

Marion is questioned about British organization in Singapore prior to the fall of the city. The new sickbay is completed. Blanche and Dorothy become friendly with the guards in exchange for cigarettes and tea. Blanche, Dorothy and Rose are cornered by three guards; when all six are caught, the Japanese commander accuses the women of lying about the almost-rape. Dorothy agrees with the him, causing Blanche and Rose to be punished, until their story is corroborated by other sources.

Punishment details are imposed on the camp in general and the escapees in particular. The commandant yields to Marion's plea for mercy for Debbie, and agrees to be release Blanche if the internees will make 500 work hats in the next seven days. The Dutch, angry that they are again being punished for British misbehaviour, insist that both groups should now be treated seperately, until they discover that making hats will release Blanche. The commandant releases the internees from punishment details on the last day, allowing the women to meet the deadline.

Christmas is approaching. The work party reports seeing a group of men in the distance. When Marion asks the commandant for names of the men, the list causes both joy and disappointment. The women are told they will be going to another camp. The commandant reveals his long-time knowledge and support of the women's subterfuge's to steal paper from his office. The women leave the camp, uncertain of their future

1 JANUARY 1943: The internees adjust to life in their new camp, where things are radically different and seemingly much more luxurious than the last one, but soon realise that luxury always has its price. The leader of the women there is Verna Johnson, who's a scheming collaborator in league with Miss Hasan, interpreter to the Commandant, Lt Nakamura. No sooner have they arrived at the camp than Christina is taken away from her friends and sent to another camp on a lorry. Marion is reunited with an old school friend, Lillian Cartland, and her little boy Bobby. Bea finds she must defer to the camp's medic, Dr Natalie Trier. Kate conceals the fact she is a nurse and Sally's attitude to life deteriorates rapidly.

15 JANUARY 1943: Punishment continues to be severe following Sally's death. Rations are cut and workloads increased. Mrs Van Meyer finds out that Joss is in fact a lady, and starts sucking up to her with no shame. Sister Ulrica goes to the priest for confession and confesses to helping with Sally's funeral, even though since she killed herself it is regarded as a terrible sin. As penance, she has to keep away from the other women and not speak to them at all. The priest says they have led her away from God. Dorothy reveals she is pregnant to one of the guards and wants to abort the baby, which prompts a shocked Sister Ulrica to break her silence.

Sister Ulrica tries to talk Dorothy out of aborting the baby: she says that its either that or she will kill herself. Verna and Miss Hasan arrange for her to have an abortion next day, but then they find out that the new district commander is coming to visit and shove them all in a storeroom for the procedure. The new commander turns out to be the newly promoted Major Yamauchi, who expresses displeasure at the camp hierarchy and replaces Nakamura with Sato, now a lieutenant. When the priest visits again and Sister Ulrica tells him she helped Dorothy get rid of her baby, he arranges for her to leave the camp and continue her imprisonment at a convent. Leaving, she tells Bea that she knew how to be a nun but she didn't know how to be a woman until she met them all.

30 APRIL 1943: The internees suffer severe punishments following Rose's escape. She is brought back to the camp alive, but shot in the back; Bernard was killed at the scene. Bea and Kate operate on Rose to remove the bullet and all of the women provide items for them to use in the surgery, even Verna. When Rose wakes up, she is paralysed from the waist down. Yamauchi and Miss Hasan try to find out how she kept in contact with Bernard. Blanche finds it hard to visit Rose after the shooting. Shinya tells Dorothy that one of the women informed on Rose and everyone suspects Christina of being responsible. She is put before the disciplinary committee and gets back a Not Proven verdict. Marion catches Lillian giving Bobby unusual food items and realises she was the informer, to get extra food for Bobby.

3 SEPTEMBER 1943: Conditions continue to worsen inside the camp, not helped any by a drought and an increased work load. Marion's diary is burned by the guards. The prisoners discover that Red Cross Parcels have been sent to the camp but not given to the women - Verna tells them they were kept from them in the aftermath of Rose's escape but Marion works out that was a lie and realises the contents of the parcels have been sold on to them by Verna. Dorothy forgives Shinya for shooting Rose as he prepares to leave for the front. Next day, an allied plane bombs the camp while trying to bomb Yamauchi's headquarters, killing Miss Hasan and Shinya and seriously wounding Daisy and Sato. Led by Blanche, the women takes advantage of the incident to raid the storerooms and steal the Red Cross parcels. Yamauchi shows up in the middle of it all and orders them to stop.

The women are met in Singapore by RAPWI officer Phyllis Bristow, who take their details, She wants to transfer Kate and Mrs Van Meyer to other groups, but they refuse and are left where they are. Alice learns that her father is still alive. They are all taken to their new quarters, at Raffles. The luxury of the hotel and the richness of the food stuns the women, as it has been some years since they have had it so good. Marion is approached by a colonel who is gathering evidence on war criminals and Kate hands Dr Trier's notes over to the medical corps. A party is held at Raffles to welcome them all back to the land of the living, where Mrs Van Meyer flirts with a colonel. Marion awaits news about Clifford and Bea runs out of the party in tears, unable to cope with everything.

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.

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.
