A look back at one of boxing's most exciting fighters in Bob Satterfield, a kill or be killed knockout artist whose kamikaze style made him a fan favorite. Satterfield lived a double life as a boxer and a pimp who ran a brothel out of his home.

The no-holds-barred real fighting series continues with even more skull-cracking action and expert commentary by Don "The Dragon" Wilson, Eddie Bravo and announcer Bruce Butler. The competitors in the "Knockout Nightmare" edition include Ken Shamrock's Lions Den, Russ Vale Todo, Medina, Wallid Ismael, Vernon "Tiger" White and Stepp. Combat grappling and millennia jujitsu are just two of the pulse-pounding events.
