*Contains some spoilers* This movie is cheesy 80s horror in all its awfulness. The plot takes way too long to get off the ground, never steadies itself, and then just plain crashes about 40 minutes into the film. There are a few gem moments for zombie fans, but not nearly enough zombies to create a real sense of terror.

The zombies also take a long time to make their appearance. First, there's a whole half of a movie about mobs and prison gangs. The hero of the movie is an ex-Vietnam vet who gets caught up in the mob. The main mob boss sets him up and he goes to jail. In this jail, they are experimenting on the prisoners to find a way to cure them of homicidal tendencies and criminal behavior. But the badie psychotic head scientist/military guy has other plans in mind. He wants to use a slightly different version of the serum to make ....da da da.... super soldiers! After some infected prisoners kill a few guards and most of the prison has a round of infected communion wine, the military/crazy scientist guy goes "hey this might be a problem" and gives a call to the genius scientist turned investigative journalist hot babe ultra-empowered independent woman character, who of course invented the original serum. She goes to the prison to see what's going down, the military guy calls in a few SWAT teams from his secure position outside the prison, and the hero guy takes charge of the few prisoners with a heart of gold when a riot breaks out. The hero guy and the scientist/journalist lady team up to find a cure, save the warden's kids, and deal with some irate prisoners, both infected and not. Meanwhile, the mob boss guy has made a deal to get into the prison so that he can save his imprisoned brother. The military gets ready to blow the place up, and everyone inside scrambles to find a way out.

There are a lot of gory scenes where people are killed by being pressed or pulled through prison bars. There's also a creepy decapitation scene and electrocution scene involving the same infected rasta prisoner. Still, the most disturbing scene is in the early part of the film, when a gross corrupt guard rapes a prisoner.

The main highlight of this film is one scene towards the end. The hero, woman, and kids are trying to make their way to the only escape route. Their path leads them to a long hallway, on one side there is a wall and on the other are prison bars. Hundreds of bloody zombie hands reach through, gracing their hair and faces as they pass by. There's also a few good scenes of the classic "couple of zombies munching on freshly dead bodies" and "many zombies ripping one guy to shreds" bits.

Overall, worth watching if you're researching the zombie genre as it has so many zombie clichés worth noting; it's practically an instruction manual on what not to do when making a zombie movie. But if you're new to zombie flicks and want a real scare, you should look elsewhere.
