When Lucy Owen (Kate Hudson) meets handsome Adam (Stuart Townsend) she thinks she has finally found her perfect man. Even better, he seems to get on well with her close-knit family, and rapidly wins the approval of her two sisters Laura (Frances O'Connor) and Alice (Charlotte Bradley). But when the devlish charmer seduces first Laura, then Alice, and even begins to turn the head of younger brother David (Alan Maher), it seems the family might be getting a little too close-knit for comfort.
