When the daughter-in-law of a prominent religious educator (guest star Robert Foxworth, "Lateline") is found murdered in her hotel room, Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) suspect an at-large burglar who recently has been breaking and entering several Manhattan hotel rooms. However, their attention later turns towards someone close to the pregnant victim where they learn that she was probably conducting an affair at the time of her slaying. Richard Belzer, Dann Florek and Michelle Hurd also star. Angie Harmon (NBC's "Law & Order") guest-stars as A.D.A. Abbie Carmichael.
