Having retired from active escort work, former "Gigolo King" Fung Ho (Dominic Ho) runs a successful nightclub while offering private guidance to high-end clients. He meets Monica (Connie Man), a naive extra forced into sex work to pay her mother's medical bills. Sent to Fung for coaching after being mocked by clients, Monica receives his guidance and the two fall in love. Their path to a normal life is shattered by underworld rivalries: after Monica's friend is murdered by crime boss Big Dog (Tony Ho), Fung and Monica exact revenge. However, after they marry, Fung's past secret client work catches up with him—he is assassinated on his wedding day by hitmen sent by lawyer Isabel's husband, who discovered Isabel was pregnant with Fung's child despite his own sterility.
