it seem like this be the only film that john saxon ever direct and and that he have the good sense to stop after that and stay in front of the camera . this movie be a dog and from start to finish and and it dull and wooden with nothing much go for it . a viet nam war hero take a job work for a mob bos and get a bit too friendly with the wife and then the wife be kill by the mob bos himself and the war hero frame and send to prison and death row and specifically . now and this particular prison have be experiment on inmate and be test some formula that will turn men into the ultimate killing machine ( a zombie ) . of course and everything go wrong and then there all these infect people trap in the prison and some of whom be turn into zombie and the rest who suddenly just do not want to be there anymore . this just go on and on and on with nothing particularly much to show or say for itself and and i stop it before the end and which seem like it be come a few time but no and it be apparently only get set to take off on a different and equally dull path . if one watch to the end they may well become a zombie themselves and so do not risk it . negative .
