Crazy Frog (Sammo Hung) has 'run away' from his wife and is out about the
town gambling. Multi-Hand Chick (Meg Lam Kin-Ming) pickpockets someone and gets Crazy Frog to protect her. She lures him into her house, whereupon she steals his prized possession, his Invincible Armor. Meanwhile, Crazy Frog's very ugly wife enlists Dirty Tiger (Lau Kar-Wing) to bring him back home. Upon meeting Crazy Frog, Dirty Tiger decides to help Crazy Frog get back his Invincible Armor. The two team up and go through many obstacles to try and get back the Invincible Armor.

A pretty funny movie, with lots of acrobatic kung-fu by both Sammo and Kar-Wing. The ending of the movie though makes it seem like you missed something in the movie.
