In the feature-length pilot episode, the small town of Twin Peaks, Washington, is shaken up when the body of high school student Laura Palmer is discovered near a riverbank, wrapped in plastic. FBI Agent Dale Cooper is called by local sheriff Harry Truman when Ronnette Pulaski, a schoolmate of Laura, is found wandering on a bridge and then slips into a coma. Cooper sees a connection between Laura's death and the murder of another girl one year earlier. After finding a piece of paper under Laura's fingernail, similar to one he found in the fingernail of the girl who died earlier, Cooper suspects that same killer might have struck again. Meanwhile, Sheriff Truman arrests Laura's boyfriend, Bobby Briggs, who is secretly having an affair with a married woman named Shelly Johnson. Afterwards, Laura's mother has a terrifying nightmare.
