 Investigating this dual homicide are police detectives Mike Leary and John Koch, who interview the drive-in's boorish manager, Austin Johnson, and the odd custodian, Germy.Germy mentions that a peeping tom likes to cruise the area to watch couples and lone girls, and he is told to try and write down the voyeur's license plate number the next time he sees him.That night, the killer strikes again, impaling two lovers while they are making out in their vehicle, and leaving a sword behind.
