Chief Vick assigns Shawn and Gus to use Shawn's psychic powers to screen a new nanny for her before she loses her mind to sleep deprivation. Though Shawn has his eyes on a string of high-profile robberies -- especially after stumbling on a crime scene where the robbery turned to murder after being picked up for harassing nannies and children in the park -- the chief demands that they focus only on the nanny-search. The two are even fired for dividing their attention -- until Shawn determines that there's a connection between the robberies and the nanny agency.
