Spartan Bare Knuckle

In the north of England, an underground fight club is pushing violence to new extremes. Spartan Bare Knuckle Fight Club is the UK's only licensed 8x8ft bare-knuckle pit fighting club. But beneath the violence, the club aims to be a lifeline in difficult times. Over seven years, Spartan has become a form of community and therapy for men battling addiction and poor mental health.
