Killers Five (1969)

A group of evil bandits are terrorizing the land from their invincible mountain castle. The high commanding official decides to put a stop to this and commands one of his officers to gather a group of Kung Fu masters to put an end to the terror. But everything is not that simple and straight-forward, as we quite soon learn when the plot thickens.

Unfortunately the movie Killers Five is not yet available on HBO Max.
