An anonymous flasher exposes himself to shoppers in the Forest Ridge Mall parking lot. The head of mall security, Ronald "Ronnie" Barnhardt (Rogen), makes it his mission to apprehend the offender. He is assisted by Charles, Dennis, and the Yuen twins (John and Matthew Yuan), in his efforts.
The next day, Ronnie's dream girl, Brandi (Faris), who works a mall make-up counter, encounters the flasher. Ronnie tries to comfort her until a police officer, Detective Harrison, arrives and takes over Ronnie's palliative role. Ronnie is upset that his boss allowed an outsider to infringe on his search for the offender.
