As far as Kung Fu movies and their parodies go, this one is perfect. The only reason I cannot give it 10/10 is that it involves comical extreme violence. That's perfectly appropriate and in fact required for this particular style of movie, but it does mean that it is not suitable for everyone.

Sing, the protagonist, is a criminal anti-hero who as a child bought an overpriced pamphlet on "Buddhist palm Kung Fu" from a scammer. When he thinks he has learned its content and tries to apply it to save a mute little girl from bullies, he is told a harsh lesson that sets his life on the wrong path.

Many years later Sing, supported by his fat friend Bone, tries to blackmail the poor tenants of a slum-like house by posing as members of the infamous Axe gang. The plot goes horribly wrong, resulting in a series of ridiculous escalations of violence between the Axe gang and the tenants of the house.

And THEN the fun starts.
