“It's a ph-f-f-frolic about man and mate from moonlight to mayhem!”

Robert (Jack Lemmon) and Nina Tracey (Judy Holliday) sign their divorce papers after eight years of marriage, each sure that single life will suit them better.

Robert and Nina keep trying to prove they're fine on their own, and neither can quite stop checking on the other.
