In Avenging Spirit the protagonist is a spirit out for revenge. He has been murdered by a group of gangsters and his girlfriend has taken hostage by them. Her father uses his brand new machine to call the man's spirit back from the dead, telling him that they are holding his daughter ransom unless he turns over his research of ghost energy.
