Susan is the manager of the Pierpont Inn in Peoria, Illinois. Her daughter Tyler Thompson and her mother Rose Thompson, the wheelchair-bound victim of a stroke, live with her. The inn is about to be sold, and people involved in advancing the sale are being killed in unusual ways. Sam and Dean come to investigate, and sneak into Rose's room to see if she is responsible for the possibly hoodoo related deaths. Susan catches them and orders them to leave. When Susan is preparing to take her daughter out of the hotel, she is nearly killed by a driverless car, but is saved by Sam.
Sam and Dean tell Susan that a spirit is haunting the inn, and she reveals that her mother's sister, Maggie Thompson, drowned in the pool as a child. Maggie tries to drown Tyler to keep her at the hotel, and Susan, Sam, and Dean cannot rescue her, but Rose sacrifices herself to act as Maggie's companion forever, and Tyler is saved.
