Shawn and Gus are on the slopes on their ski vacation in Whistler, British Columbia when Shawn spots wanted international art thief Pierre Despereaux (Cary Elwes). Despereaux is so good, he's never left enough evidence behind to be formally accused and so promptly gives Shawn and Gus the slip. Lassiter and Juliet arrive in Canada just in time to meet Shawn and Gus at Despereaux's latest crime scene.
