Survivors

Abby stumbles across a community that could hold the key to everyone's future. The last surviving member of the government, Samantha Willis, has established a community which still has light, food, hot water and power, but to what lengths will she go in order to maintain control? Greg and Tom encounter a family who have successfully sheltered from the virus but when the daughter reaches out to them they face a terrible dilemma.

When Abby learns of a group of young boys living in a nearby mansion, she leaves her new friends in the hope of finding her son. Arriving at the mansion, she finds herself in the middle of a land dispute, and must broker a truce if she is to find Peter. Meanwhile, Tom, Sarah, Al and Najid are drawn to the comfort and security of Samantha's community, and Greg and Anya encounter some unwelcome visitors.

Suspicions are aroused when visionary spiritual leader John turns up mysteriously at the survivors' door with his ragged group of passionate disciples. Is he as innocent as he seems, or does he have more sinister intentions? When Abby allows a pregnant woman from John's group to stay with them until the baby is born, Anya fears that she will be forced to reveal that she is a doctor. John makes Anya fear for the group's safety.
