Trefelin is deserted as Prem waits for a vaccination unit to arrive from Cardiff. But Reverend Todd is still determined that only he can save the village, and wastes no time in telling the villagers that God has stepped in where Prem's medicine has failed. The community seems oblivious to the deadly outbreak that it faces, and Prem seems to be losing the fight. While Prem tries in vain to round up the villagers for immediate vaccination, Todd discovers his daughter Verity's affair with a married man and decides on a severe punishment. An exasperated Prem decides to call in the law to help him. And his battle with Todd for control over the village reaches a head when suddenly another man falls seriously ill.
