After being mistaken for an addict, Tim is welcomed in by an eccentric religious community who set their sites on his spiritual health.

An open casting for actors in a period biopic leads Tim to a role as an extra, which quickly turns to him replacing James Norton as the disabled lead, with chaotic results.

Tim gets scouted as a drug dealer but soon realises it isn't as fun as it looks on TV, while Ruth is left to look after his new care dog, Snuffles.
