He’s intrigued at the possibility of fatherhood. And when a business trip takes him to San Francisco, where the boy was last spotted, he decides to make a few inquiries. Meanwhile, Collette springs the same fatherhood news (and photo) on Dale Putley, a despairing writer and another old flame. Dale, who has no life to speak of, throws himself wholeheartedly into the mission. Inevitably, the aspiring fathers bump into each other, compare notes and squabble over paternity rights. When they confront Collette, she tells them she’s unsure which one is the real Dad. -- Desson Howe
