Pembrokeshire – 1994. Mostyn Thomas is an ageing farmer, down on his luck, on the brink of bankruptcy. When he runs into Jethro, a young raver, his fortunes appear to take a positive turn. The pair hatch a plan to solve Mostyn’s money problems by holding a rave on Mostyn’s secluded land. Secretly mobilizing the locals of the village pub they plan the greatest money-spinning event in the history of Little Emlyn: Lewistock.
