When visionary spiritual leader John turns up mysteriously at the survivors' door with his ragged group of passionate disciples, some in the house are suspicious of his motives, in the penultimate episode of Adrian Hodges' post-apocalyptic drama series.

Charming and eloquent, John is a preacher with a unique perspective on the new world, but the family's opinion of him is split. Is he as innocent as he seems, or does he have more sinister motives? A woman in John's group is pregnant, and Abby allows her to stay until the baby is born. Anya fears that she will be forced to reveal that she is a doctor if there are any problems with the birth. Worse than that, she picks up on some unusual remarks by John which make her concerned for the group's safety.
