Psych is a quick-witted comedy starring James Roday as young police consultant Shawn Spencer, who solves crimes with powers of observation so acute that Santa Barbara PD detectives think he's psychic. Psych also stars Dule Hill as Shawn's best friend and reluctant sidekick, Gus, and Corbin Bernsen as Shawn's disapproving father, Henry, who ironically was the one who honed his son's "observation" skills as a child.
