Yiu Chun-Man, a gay fashion designer in Hong Kong, gets a visit from twin brother Yiu Chun-Kit. Kit is visiting from Thailand and promptly takes Man's expensive car out for a spin and gets into a horrendous accident in which a woamn dies, and Kit was driving with Man's license.

Since the revelation of Kit's true identity would be a real legal tangle, Kit is forced to assume Man's identity and vice-versa. Even worse, Kit is now in a coma, meaning Man has to hang out at his bro's bedside hoping that he can clue him into the switcheroo as soon as he wakes up.
