Deadly Games (1970)

Sinopsis

Former undisputed MMA champion Dax Gage returns home after a seven-year prison stint to find his life in ruins. His estranged father wants nothing to do with him, his marriage has crumbled, and his younger step-brother Maverick — once MMA’s most promising star — is barely staying afloat with a newborn on the way. Drowning in debt to London’s most feared loan shark, Maverick is forced into the Deadly Games—a brutal underground tournament offering a £1 million prize.
