Recent widower Frank Hardcastle is surprised by a party thrown by the tight-knit community of Glan Mor to celebrate his 71st birthday. He is shocked to see his daughter Carys show up with her son Dylan.
Carys and Frank agree on a new strategy of themed weekends. The first event is a great success - until two rival re-enactment factions, drunk on moonshine, start fighting, and it is up to Frank to break it up.
Inspired by Royston's old-skool Northern Soul type dancing, and annoyed that a rival caravan park is nabbing all their customers, Carys decides to hold a Take That tribute night.
