 Five months after the birth of his son, Mel Coplin remains unable to name the child until he has met his own biological parents and discovered who he "really is." He, his wife Nancy, and his social-worker-in-training Tina Kalb jet off to California to meet his birth mother--who turns out not to be his mother, due to an error with the agency s adoption records. The quartet sets out in search of Mel s real parents, with tensions growing because of the sexual chemistry lacking between Mel and Nancy and growing between Mel and Tina.
