When Police kicks open the doors of the elite underground fight club Knuckledust, they find seven levels of hell, filled with the dead bodies of countless fighters, assassins and goons. Only one man, beaten up to a pulp, is still breathing: Hard Eight.
Unfortunately the movie Knuckledust is not yet available on HBO Max.
