After twenty years five old friends are reunited for the funeral of an acquaintance on an abandoned island off the west coast of Ireland. Trapped by a sudden storm, they end up stranded overnight, alone, drunk and marooned on this desolate windswept rock; but when morning comes only four of them leave. Bonded by this terrible pact, this crippling secret which forces them to rekindle old fires, they desperately try and stay one step ahead of the law. And each other.
