Four guys with an interest in competitive rowing - ad executive Scott, architect Michael, stockbroker Bob, and college professor Walter - decide their crew needs some help. They learn that the daughter of an Olympic rowing champion lives in town, and she's no slouch at the sport herself. The four approach Kimberly and discover that she happens to be a very beautiful woman. For the sake of the team, all four make a solemn vow not to make any romantic overtures to Kimberly while they're in training, but predictably the flesh is weaker than the spirit and all four end up dating her at one time or another. The real dilemma comes when Kimberly becomes pregnant, and she isn't sure which one of the four men is the father.
