Villain defeated by backwards firing gun

Elliot Ness, an ambitious prohibition agent, is determined to take down Al Capone. In order to achieve this goal, he forms a group given the nickname “The Untouchables”.

Special Agent Eliot Ness and his elite team of incorruptible agents battle organized crime in 1930s Chicago.

A man is continuously vilified by the other members of the small community in which he lives. One day he meets a strange "doctor" who offers him a great ability with the gun through mysterious magical arts. The man accepts and his vengeance begins. But the price to be paid for the newly acquired skills could be too high.
