Shawn and Gus get called in for an important meeting in Chief Vick's office but when they get there they are surprised to find Special Agent Lars Ewing of the Treasury Department, who is in town on a counterfeiting case and has brought along his partner, Lindsay Leikin, a psychic who not only has had great success on this case already but is determined to prove Shawn a fake.
