The Purifiers

Dominic Monaghan starts as a member of The Purifiers, a gang of martial arts experts with a fierce reputation for protecting the streets.
Tired of hopeless government initiatives and bad policing, Moses (Kevin McKidd), the leader of a rival gang attempts to unite the neighborhood into an all-powerful confederation with complete control over street crime and the drug trade. Because this goes against everything the Purifiers represent, they find themselves standing alone, and it soon become clear that for the new alliance to succeed, the Purifiers need to be eliminated.
With the odds stacked against the Purifiers, explosive and volatile street fighting reaches all-new heights with very different and deadly outcomes in the balance. (official distributor synopsis)
