Plot

The town of Glyngolau, Wales, has lost its coal mine and steel mill, leaving everyone in financial ruin. A large factory complex, offering 1,000 local jobs, is being built in the town by Kallbridge Developments for a Japanese firm. Iwan, head of the town council, worked hard to secure the project. Iwan's 15-year-old daughter, Leona, is a juvenile delinquent and small-time drug dealer; his wife, Polly, catches Leona in bed with a 30+ year old man. Leona takes eight of her teenage friends to sneak into the building site, to cause destruction and "annoy my Dad".
