Adam (George Segal) is an English instructor at a U.S. college who hopes to win a professorship and tenure. Tricia (Glenda Jackson) is an English divorcee. They both wind up on a French ski slope at exactly the wrong time, and in the resulting collision, break one another's legs. While they are slinging ever-wittier insults at each other, they are also falling in love. They soon wed, with Tricia joining Adam back in the States. There, it becomes clear that Tricia was not cut out to be a dutiful, meek professor's wife.
