This is a sequel to He's a Woman, She's a Man, so it's best to view that film first. This one focuses more on the relationship between Wing (Anita Yuen) and Sam (Leslie Cheung). Wing continues her career as a boy singer, and since she moves in with Sam, everyone assumes that he is gay.

Wing asks downstairs neighbor Fan Fan (Anita Mui, Wu Yen) to pose as Sam's girlfriend to help with the gay rumors (not realizing that Sam slept with Fan Fan). Wing becomes attracted to Fan Fan, and Fan Fan wishes that he weren't gay, as she is attracted to him as well. Sam suspects that they are in love, so tells Fan Fan that Wing is a woman. Wing and Fan Fan end up making love, throwing all three of them into a tizzy.

In the midst of all of this, Wing and Fan Fan take parts in a movie in which they are crossdressers. Wing is a woman playing a man playing a woman, and Fan Fan looks great in a mustache and tux.

It's a gender-bending sex farce, and although it doesn't quite live up to the first film, it's still fun and with more lesbian action this time.

Also present in the film is Fan Fan's friend O (Theresa Lee), a lesbian who hangs around in bathing suits and rollerblades. She ends up having sex with Wing's friend Fish (Jordan Chan), but only if he dresses like a woman.
