The film opens with Tom and Sarah in the airport, then flashes back from the moment they met up to the present. Working-class Tom Leezak and upper-class Sarah McNerney meet up when Tom accidentally hits Sarah with a football. A few months later, despite opposition from Sarah's rich family, they get married. They have kept a secret from each other: Tom doesn't tell Sarah that he accidentally killed her dog and Sarah doesn't tell Tom that she slept with Peter Prentiss, a childhood friend and her family's friend, after she and Tom started dating.
