Director and screenwriter Walter Hill returns to one of his favorite themes -- desperate and violent men using force to escape from an unforgiving environment -- in this action drama set behind bars. Monroe Hutchen (Wesley Snipes) was once a promising heavyweight contender until he was convicted of murder and sentenced to life without parole at the Sweetwater maximum security prison in California. Now, Hutchen boxes behind bars, and he's become the champion of a loosely organized prison fighting circuit. When heavyweight champion James "Iceman" Chambers (Ving Rhames) enters Sweetwater after being convicted of rape, Hutchens finds the serious competitor in the same lockup for the first time, though Chambers scoffs at the jailhouse champ. After Hutchens challenges the arrogant Chambers to a bout, aging mafioso Emmanuel "Mendy" Ripstein (Peter Falk) swings a deal that will earn Chambers an early release from prison and pull in a million dollars in bets from guards and inmates if the two men will meet in the ring for a last-man-standing bout without referees. Undisputed also features Michael Rooker, Fisher Stevens, rapper Master P, and former Yo! MTV Raps host Ed Lover.
