Joanne and Alan are husband and wife, who work in the same advertising office. Alan is too quick in bed and Joanne ( Chik King-Man) is becoming less satisfied. And drop-dead gorgeous Yvonne (Yamaguchi Keiko), a co-worker, finds Alan so attractive that she stays back late just to ask him to accompany her to the (men’s) toilet. Joanne takes French lessons, and meets bi-sexual photographer Terri (a gwailo) in one of the classes. Joanne and Terri (Maria Tung Ling) drift closer and become lovers. The agency needs a nude model for an ad, so Joanne introduces Alan to Terri, who convinces Joanne to model for the ad. Alan finds himself attracted to the plain-looking Terri, but her explanation to Alan of why she goes with women is weird, to say the least. It seems all her ex-boyfriends either died while crossing the road or committed suicide, and she’s therefore afraid of loving a man again. There’s also Terri’s live-in lover (a pretty blonde girl with an apparent distaste for clothing), whom she dumps. After just one more great sex scene with Alan, Yvonne vanishes from the picture . Terri wavers between being a shoulder to cry on and being a lover to both husband and wife.
