The episode centers on the discovery of Hae Min Lee's body in Leakin Park by a man named Mr. S. Detectives Ritz and MacGillivary immediately find his story suspicious, particularly why he walked 127 feet into the woods to urinate. Their interrogation reveals Mr. S's criminal record for indecent exposure, including a recent incident. He fails an initial polygraph but passes a second, leading him to fade as a suspect. The host investigates Mr. S's background, finding no connection to Adnan or Jay, and speculates that his history makes it unlikely he would seek police attention, suggesting his story might be truthful. The episode concludes by shifting focus back to the boyfriends.
