Marty, a college student in New York, decides to pay his family a visit in their ancient and imposing house in D.C. He makes two mistakes, one is bringing his fiancé, Lesly with him, and the other is coming at all. As soon as he gets home things begin to go wrong, and although the mother, Mrs. Pascal hides the kitchen knives, she isn’t able to prevent disaster. It soon becomes clear that Marty and his sister, the unbalanced Jackie-O are just a little too affectionate towards each other, and everything untoward that could happen, does, in this unusual comedy about a house where the word “no” is never heard.
