An innocent man is found guilty of murder and sentenced to death, but as he's about to be hanged he accidentally kills his executioner. He now faces a new trial, presided over by a young and inexperienced judge.
A one-handed madman (he lost the hand while escaping a hanging) uses various detachable devices as murder weapons to gain revenge on those he believes have wronged him.
When a cavorting Hollywood writer is killed by the angry husband of a woman he was having an affair with, he comes back as a spirit in the form of a beautiful woman and moves in with his/her best friend as a base operation for enacting sweet revenge.
