Miles Teller stars in this drama based on the life of professional boxer Vinny Pazienza. Shortly after winning the junior middleweight world title, Vinny Pazienza (Teller) is involved in a near-fatal car accident which leaves him with multiple injuries including a broken neck. Told he will never walk or fight again, Vinny is fitted with a metal neck brace which he must wear for several months. However, defying doctor's orders, he continues to follow his training regime and, with the help of trainer Kevin Rooney (Aaron Eckhart), Vinny remains determined to prove his doubters wrong and vows to make a triumphant return to the ring to reclaim the world title he relinquished one year earlier.
