Dad David desperately tries to get a promotion within the church. But his plans are made difficult by Andrew, his Lycra-clad, holier-than-thou neighbour.

David unearths an ancient religious rulebook and uses it to police his family. But he's not sure how to interpret the decree to 'never boil goats in their own milk'...

Rachel meets a supposedly pious girl at church who changes her perspective on dating. Struggling to get Fiona's attention, David gets date ideas from a sex education class.

Fiona's frustrations with David lead her eyes to wander down the road to Lycra-loving neighbour Andrew, and David's confession about his 'Tupperware of Sin' doesn't help matters.

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.

At an annual cross-church party, Aaron waits to be baptised. But his head is turned by one congregation carrying rainbow flags. Fiona and Rachel argue over university.
