安妮（琳赛·洛翰LindsayLohan饰）和荷莉（琳赛·露安LindsayLohan饰）两个小女孩在夏令营中相识。她们相貌惊人地相似，却非常合不来。十分偶然的，她们知道了对方原来是自己的孪生姐妹。她们开始互相打听对方的生活，讨论自己的父母：他们在一个豪华的航海轮船上相遇，在旅途中就结了婚，然而最后却以感情破裂收场。Because of this divorce, one of the twin sisters was brought to California by their father (Dennis Quaid) and lived in a beautiful vineyard; the other was taken to London by their mother (Natasha Richardson), who was a wedding designer.两人因此从未谋面，甚至不知道彼此的存在。得知了这个真相，两个调皮的小鬼开始谋划她们的计策：她们决定调换身份，到对方的家庭去生活。Everything goes well until the father is about to remarry, and a crazy sniper battle between the sisters and stepmother (played by Elaine Hendrix) begins... The film is remade from the 1961 version of the American movie "Dad Loves Mom".年仅11岁的琳赛·洛翰凭借在片中一人分饰两角的表演，荣获1999年美国“艺术新秀奖”最佳年轻女演员奖。
