Interim Chief Vick and Detective Lassiter are out of town on their way to a seminar on non-lethal weaponry, which leaves only Juliet to deal with a mother who comes to the station claiming her son, Malone Breyfogle, is missing. However, since her son is 18, the police can't get involved for 48 hours. Juliet believes something has happened to him, and so she enlists Shawn's help to investigate immediately.
