Will and his brothers are on holiday in a cramped caravan on the wild irish coast. All the boys love ghost stories, but one dark night Will's older brother, Marty, tells the bloodcurdling tale of the cutthroat pirate, Captain Crow. Will is scared. From that night on, everything starts to go wrong for Will. He is embarrassed by a girl at the local youth disco - The Sprat's Jig - and Marty convinces him that the ghost of the evil Captain Crow is out to get him. But Marty's tricks backfire, and for once Will has the last laugh.
