This lively and complicated romantic comedy-drama centers on four fellows. Runyon is a poet carrying a torch for Kathryn; he flies to LA to talk about scripting a movie and is accompanied by the lovely Tarzaan. Gadabout Josh is seen having a fling with a Chinese hat-check girl and pursuing Cynthia; despite his womanizing, he also still cares for his ex-wife Gina, the sister of Phil, a plumber and owner of a hardware store who is married with two children. Phil is in a quandary because he finds himself lusting for a sophisticated English coquette who just might be interested in him. Meanwhile, therapist Mark is utterly wrecked over a difficult relationship with Tasha. The title of the film comes from a line in rocker Steve Miller's song, "The Joker".
