After one last big score, a master diamond thief retires to a secluded island paradise with his wife, who happens to be his criminal partner. He promises her that their criminal lives are behind them, but finds himself tempted when his arch-nemesis, a wily FBI agent, tracks them down to make sure that their retirement is legitimate. A cruise ship with a massive diamond on display happens to be docking at their island for a week, and the game is afoot.
