On Halloween night in 1985, Shawn and Gus witness a troubled girl throw herself from her window at the Wispy Sunny Pines mental institution. From that moment on, "Scary Sherry" has haunted the hall...
Psych stars James Roday as Shawn Spencer, a police consultant who solves crimes with powers of observation so acute that the police think he's psychic - or so he lets them believe. Also stars Dulé Hill as Shawn's best friend and reluctant accomplice, and Corbin Bernsen as Shawn's disapproving father, who ironically was the one who honed his son's "observation" skills as a child. Also featured are Timothy Omundson, Maggie Lawson and Kirsten Nelson.
