The Cut centers on a once-great Irish boxer who has walked away from the sport and now lives a quieter life running a gym with his partner, Caitlin. When a rare chance at one last championship fight comes along, he agrees—but only if Caitlin will train him. To be eligible he must make an extreme weight cut, forcing him into days of brutal dieting, dehydration, saunas, pills, and ruthless methods under the direction of a hardened trainer. As the deadline nears, the toll on his body and mind grows severe, pushing him to the edge of sanity and making him confront haunting memories and the sacrifices he’s willing to make for one more shot.
