The third RE-ANIMATOR film finds Dr. Herbert West (Jeffrey Combs) getting out of jail after fourteen years for inadvertently killing a young girl as a result of one of his experiments. During his time on the inside, West continued to perfect his methods on rats. When a young doctor who is aware of West's discoveries, becomes the new prison M.D., he asks West to help him on a project he is working on. Before long, dead bodies are being reanimated left and right, and the prison walls are running red with blood!
Once again tampering with mother nature to disastrous results, Dr. Herbert West continues his research while serving time in a maximum security prison for his previous exploits. West's limited prison-cell experiments are suddenly interrupted by the arrival of a new prison doctor and the brother of the girl who suffered from West's experiments 13 years earlier. -- Description provided by TMDb
