It's mate-swapping, Radley Metzger-style, as the maestro of chic screen sex captures the exploits of two suburban couples involved in wicked carnal games. Their heated roundelays lead to a kinky confrontation where sexual preferences head off into lesbian and bisexual directions. Lynn Lowry, Claire Wilbur, and Calvin Culver star. Uncensored version; 92 min. Widescreen (Enhanced); Soundtrack: English; audio commentary by Metzger; featurette; interview; trailers.
