Davie is a dreamer, constantly hustling for his next buck, then losing it on the horses. After a football injury, Davie falls for trainee nurse Shona and tries to impress her by running a disco. Along with friends John and Scot, the trio start promoting bands - culminating in a hugely ambitious IRON MAIDEN gig at the Caird Hall, Dundee. With ambition so grand they go deep in debt with Fergie, a gangster of legendary violence, Davie needs to use every trick in the book to pull off the biggest scheme of his life.
