The Five Lucky Stars, one of them being replaced by a younger brother, are assigned by the police to allow an actress to live with them.

Throughout the course of the movie, the Stars chase the attractive woman around the house, though their efforts are largely unsuccessful.

At the climax, the three assassins eventually end up at a recreation building to take down Swordflower (mistaking her to be their target), but coincidentally Kidstuff and his friends are there and they recognize one of them, with help from the actress.

Muscle and Ricky arrive in the nick of time and a showdown takes place, eventually ending with the protagonists victorious.

On 30 June 2003, DVD was released by Hong Kong Legends at the United Kingdom in Region 2.
