S1E21: Fighting Cage (1)

Reno receives a video tape as proof that his estranged brother Mitch is still alive, despite being declared dead in Vietnam by the military many years prior. The video tape depicts Mitch competing in a rather sketchy underground cage fighting tournament. Reno decides to enter this strange underground world and investigate his brother's disappearance by posing as one of the fighters. He soon discovers that his brother has been brainwashed, and rescuing him from this dangerous and barbaric lifestyle will not be quite as easy as he once thought.
