A hard and unsparing look at the work of wrestler KASAI Jun, nicknamed Crazy Monkey, who competes mostly in so-called death matches, a brutal style of wrestling focused on bodily harm. At times fun and exciting, at other times brutal and melancholy, the film shines a light on a subculture that has long remained in the shadows.
