This film begins with a robbery. It's a nasty affair--as they use poisonous gas to get the money. After leaving with the loot, one of them Curtis Hook (Jim Brown), betrays his partners--shooting them and hiding the money. Unfortunately for Hook, he's soon caught and sent to prison. Hook plans on just doing his time on a minor charge and collecting the money after he is released. But when he learns that the place where he hid the money is about to be demolished, he decides he must escape and reclaim the money instead. Plus, if he doesn't get out of the slammer soon, someone is bound to kill him, as practically EVERYONE seems to have it out for him.
For fans of old-time TV, this is an interesting film, as two of the most deadly tough guys in this prison are played by Frank DeKova ("F-Troop") and Ted Cassidy ("The Addams Family"). However, it's not the sort of film you might expect from these guys---it is VERY rough--with foul language and lots of violence. Plus, EVERYONE seems bad in this one--everyone. While Hook is terrifically amoral, so is everyone else--the guards, the gangs, the blacks and the whites. Because of this and because Hook is affiliated with no one, it is clearly NOT a blacksploitation film--just a very gritty prison flick. While it's not a great film (mostly because I hated EVERYONE), it was very good and well worth seeing.
