David takes Aaron to a caravan for some father-son bonding, but there's no electricity and the only running water is leaking through the ceiling. Fiona hosts a girls' night.

David unearths his order's 1000-year-old rulebook, and demands his family follow it to the letter. Fiona starts her own business in defiance of the order's traditions, and Rachel tries to obtain a mobile phone. Aaron helps his dad to convert a non-believer, but his harrowing artwork of the apocalypse makes the wrong impression.
