Soul Vengeance, Penitentiary 2) and tells the tale of a black man named Too Sweet who is imprisoned after being attacked by two bikers and killing one in self defense. Naturally the fight happens amongst white folk and since this is the 70's its safe to say they were racist white folk.
Eventually Penitentiary turns into a boxing movie that makes Rocky look like The Sound Of Music. A boxing league is formed and the winner gets to spend the night with a woman. There are some good looking chocolate mama's in this flick and we do get some naked flesh. The fight scenes are pretty cool as well and while its not quite Raging Bull, Penitentiary makes for a good knock-em-out flick. We also get some awesomely typical blaxploitation dialogue and the big life affirming speech comes from an old man who has spent almost his entire life behind bars. There is also a bit of an unexpected twist in the plot which was nice to see and makes Penitentiary perhaps just a step above the average 70's blaxploitation film.
Apparently the sequel is even more entertaining on a much more exploitative level but I have not yet seen that one. However it is on the list of things to watch before I die and the sooner the better. This movie makes prison look scarier then any other with the exception of maybe Zombie Death House and if I learned anything it is to keep your ass out of jail.
