McCall (Stepfanie Kramer) takes a sudden leave of absence to prevent her former partner, embittered renegade cop Gus Trancus (David Ackroyd), from fulfilling a contract as a professional hit man. Owing her life to Trancus, McCall hopes that she can stop him before he completely ruins his life--but she may be fighting a losing battle. Meanwhile, Hunter (Fred Dryer) is not only saddled with wimpy Sgt. Terwilliger (James Whitmore Jr.) as temporary partner, but he's also having a great deal of trouble getting the higher-ups off his back long enough to locate Dee Dee and keep her from harm. Arthur Rosenberg makes his first series appearance as Captain Lester Cain. ~ Hal Erickson, Rovi
