S4 E22: When a Congressional witness is found dead, the Angels investigate plastic surgeon Paul Redmont's association with racketeer Vern Maddox, who they learn wants plastic surgery to change his identity. Kris and Bosley pose as a couple seeking cosmetic surgery for Bosley, while Tiffany gathers information posing as a nurse. Redmont's girlfriend and former revolutionary, Barbara Brown, arranges for Maddox's surgery. But when nurse Elena discovers Maddox's true identity as the million dollar swindler of government pension funds, Barbara kills her. Barbara then forces Tiffany to replace Elena during the surgery of Maddox and she blackmails Redmont into completing the operation. The other Angels burst into the operating room where they subdue and apprehend Barbara and Maddox and inform Redmont that his very professional work almost changed their suspect's identity.
