Fathers' Day (1997)

Jack Lawrence is a successful Los Angeles attorney. He's got a good job, a lovely wife, a nice home, a great car--aside from a limited amount of patience, Jack has pretty much every thing he wants. Dale Putley has been on the brink of despair for so long that he's starting to enjoy the view. A would-be writer scraping out a threadbare existence in San Francisco, Dale is a bundle of neuroses just waiting to unravel. Dale needs something to worry about in his life besides himself. Suddenly, before you can say "romance from the past," Jack Lawrence and Dale Putley, two complete strangers and polar opposites, are sharing a car, pooling their wits, and rethinking everything about themselves as they try to track down a teenage runaway that each believes might be his son.
