In this fourth-season opener of Law & Order, Robert Klein guest stars as controversial, confrontational TV talk show host Rick Mason. During one of Mason's broadcasts, a guest is murdered on the air (and this show was telecast long before the Jenny Jones affair). The DA's office endeavors to prove that Mason provoked the tragedy -- and that, in so doing, he is himself an accessory to murder. Jill Hennessy and S. Epatha Merkerson join the regular cast as, respectively, Assistant DA Claire Kincaid and police lieutenant Anita Van Buren. ~ Hal Erickson, Rovi
