Teenage boys just messing around uncover a dead body by accident and the CSIs immediately understand the cause of death; the head of the body was complete packed in with tape. But when a dizzy man walks into the crime scene claiming someone is trying to kill him, the team splits up to investigate both cases. However, one of the cases turns quite odd when a key lock is found inside the taped head leading them to some sort of sex party. Meanwhile, the man who jumped into the crime scene turns out not only to be addicted to drugs, but also has a long rap sheet.
