I remember this well, this was when MMA was still being called the term NHB(No-Holds-Barred) and examines fights around the world. You see glimpses of true Vale Tudo in Brazil, where headbutts, knees and elbows really don't have the rulings and restrictions held in UFC and Pride, and is closest to a street fight as there are no gloves. This is the highlight if you can't seem to find fights from Brazil.
Fights around the world here in bare knuckle MMA, showed the interviews of each fighters mentality in the ring/cage, and their backgrounds.
You'll see originators here, Frank Shamrock, Enson Inoue, Randy Couture, Kevin Randleman.
It's a look into early MMA, the views before UFC blew up onto basic cable reruns, and is violent in examining the growing pains. You can tell these were the early years as today most professional fighters are very well balanced in all aspects.
