Survivors (1975)

S3E1 Manhunt

Six months have passed since Greg, Agnes, and Jack left Whitecross. Seth discovers Jack feverishly wandering in the woods and takes him to his home for care. There, he uncovers letters addressed to Charles and Jenny from Greg. Meanwhile, Charles, Pet, Jenny, Hubert, and the children have relocated to Challoner. Upon hearing about the letters, Jenny and Charles rush to Seth's place. Jack, in a delirious state, mumbles about a location called Wellingham, where he and Greg had been. An anxious Jenny longs to reunite with Greg, prompting her and Charles to set off for Wellingham, with Pet sending Hubert to follow them. After rescuing a man tied up in the woods, they encounter the domineering Clifford and the menacing Miedel, raising their concerns about the troubling situation they’ve stumbled into.
