描述两个性格迥异的亲家老爷相处的趣事。编剧安德鲁．伯格曼写出一个令人猜不到剧情发展的剧本，导演阿瑟．希勒也拍得轻松爽朗，令人笑口常开。艾伦．阿金饰演生性严肃的牙医，他的女儿即将嫁给彼得．福尔克的儿子，双方家人势不可免要互相了解一番。但福尔克是个疯疯癫癫的怪人，他声称自己是中央情报局的特务，他带着阿金上山下海，从华盛顿的屋顶跑到中南美小国的地底，途中当然碰到了不少妙不可言的遭遇。其中有些场面尤为无厘头，但有令人捧腹的效果。

The In-Laws is a hilarious action comedy starring 5-time Emmy Award winner Peter Falk (Columbo, The Brink’s Job, The Princess Bride) as CIA agent Vincent Ricardo and Golden Globe winner Alan Arkin (Catch-22, Grosse Pointe Blank) as dentist Sheldon Kornpett. Sheldon is a dentist from New Jersey, Vincent travels a lot on business. Sheldon’s got a successful practice and Vincent’s got a dubious past. In 48 hours Vincent’s son is marrying Sheldon’s daughter and what happens in between will bring them together for better or worse. Arthur Hiller (Love Story) directs the car chases, gunfights and witty one-liners, extracting perfect chemistry between the two leads as they adventure across South America together.
