Shortly after contacting her friend Mark for help, wrestler Kate Murphy dies during a match. Recognizing that Kate's death was no accident, Mark decides to follow-up on his friend's suspicions that wrestling promoter Marty Torrance is behind the disappearance of a number of young woman. Upon assembling a plan of action, Hardcastle asks friends Lucy and Denise to go undercover as wrestlers. Posing as a wrestling promoter, Hardcastle has Denise, using the alias of "White Lighting" challenge Nancy Mack, one of Marty's wrestlers. Impressed with Denise's ability, Marty agrees to a match and allows Hardcastle's team to train in his gym. Furthermore, Marty, seeing potential in Lucy, asks the "wrestler" out on the date. Although Lucy only goes on the date to get evidence against Marty, the promoter has his own plans. Before Lucy is able to contact the judge, however, Marty prepares to sell her to a white slavery ring. Worried about Lucy, Hardcastle confronts Nancy. Having suffered a falling out with Marty, Nancy comes clean and tells the judge about Marty's plans. Searching the promoter's house, Hardcastle and McCormick come across the location of Marty's meeting with the slavers. Thanks to Mark's driving expertise, Hardcastle arrives at the meeting site in time to rescue Lucy and stop the slavers.

Not wanting to continue cleaning up the estate, Mark hires Millie Denton, his former prison cellmate's widow, as a maid. Meanwhile, Hardcastle begins looking into the suspicious death of a lawyer named Charlie Clarkson. Taking over Charlie's practice, Hardcastle interviews Loni Summers, a model that had previously hired Charlie to handle her divorce. Discovering the divorce is now off, Hardcastle checks into the background of actor Dex Falcon, Loni's husband. Investigating, the judge discovers that Falcon had secretly been receiving millions of dollars from an attorney named Wendell Price. In the meantime, Millie, who claims to be a psychic, has a vision of Mark's murder. Ignoring Millie's warning, Mark proceeds with the case. To Mark's regret, he is captured by Price, shot and left for dead. Thanks to Millie, Hardcastle locates Mark in time to save his life. Next, based on the evidence Mark had gathered, Hardcastle and the police, having already taken Falcon into custody, movie in and arrest Price. As the episode ends, Millie, shaken up by her visions, decides to quit and move in with her sister.
