PEP is based on a true story about former world champion Willie Pep, the man with the most wins in boxing history. Set in 1965, Pep is living in relative obscurity in his hometown of Hartford. Amidst personal troubles, and with the need to earn, Pep, at the age of 42, makes a stunning return to the ring. The New York Times designated Pep's comeback in 1965 a "Top 10 Human Interest Story."
