S1·E13 The Chameleon

PSI asks the Powells to chaperon six contestants of the Miss Fitness USA contest. Although Dani initially believes her biggest concern is keeping Cody away from the contestants, she realizes that she has bigger problems when she runs in to promoter Buddy Rydell, a man she knows from her days as con-artist Wanda Talbert. While Cody deals with the romantic advances of Cindy Davies, one of the contestants, Dani attempts to stop Rydell from blackmailing her about her real identity. Arriving at Rydell's hotel room, Dani discovers that the promoter has been murdered. After checking fingerprints found at the scene, the police learn that Rydell was killed by an escaped mental patient named Diane Peters. Investigating further, PSI discovers that Diane killed Cindy Davies. Realizing that Cody is alone with Diane, Dani rushes to help him. Dani arrives in time and Diane is taken into custody.
