A group of bored Roman Catholic teens from Belfast, Northern Ireland, United Kingdom, steal cars and joyride around the city, causing havoc among the nearby Protestants and local Irish Republican Army members, all of who are outraged by the youths' nihilism. The gang, led by ace thief Sean, is connected with the IRA but couldn't care less about the group's politics. But things turn serious when an IRA member captures one of the boys, Marley, in an effort to end the mayhem.
