Impurity (2015)

Shotgun Jimmy is a nasty piece of work. Ripping off drug dealers, killing policemen, he'd decapitate his own grandmother for a sack full of loot. Schizophrenic, psychopathic, his only friend is Mary the Shotgun - his trusty, reliable pump-action. But during a violent road-rage incident, something goes horribly wrong and Jimmy finds himself chained in shackles in a dark, grimy dungeon where he ponders over a deeply buried secret past...
