Adopted as a child, new father Mel Colpin decides he cannot name his son until he knows his birth parents, and determines to make a cross-country quest to find them. Accompanied by his wife, Nancy, and an inept yet gorgeous adoption agent, Tina, he departs on an epic road trip that quickly devolves into a farce of mistaken identities, wrong turns, and overzealous and love-struck ATF agents.
