Neil and Sarah are the ultimate happy couple. Until, that is, Neil's new job leaves Sarah alone to juggle the baby, domestic drudgery, and her own career. When Neil fails to come home one night, Sarah rushes home to her mother, who has always wished that Sarah had married her childhood sweetheart, the fabulously rich lawyer Colin, who has coincidentally reappeared in her life.

The stage is set for divorce, but Neil has other ideas. Distraught at the prospect of losing Sarah and recognizing what an idiot he has been, he enrolls in an experimental "School for Husbands," a clinic aimed at helping hopeless spouses mend their ways. But will its intensive tuition in everything from emotional self-expression to putting the toilet seat down be enough to get Neil back together with his wife? Not if Colin and Sarah's mother have anything to do with it.
