Coming up on Law & Order:

Emmy Award winner S. Epatha Merkerson gives a scorching performance as Lt. Anita Van Buren when a case close to the lieutenant provokes her to overstep the boundaries of the law -- and a friendship -- in pursuit of a serial misogynist on Wed., Nov. 30, at 10 p.m. on NBC. "This episode tests this character in a way I don't think she's been tested before," said Merkerson. "She really does cross the line."

In the episode entitled "Acid," a young woman, her face horribly scarred, is found hanged inside her apartment. Lt. Van Buren recognizes the victim as the eldest daughter of a dear college friend and directs Detectives Fontana and Green on a no-holds-barred mission to catch the serial abuser who threw acid in the deceased's face months earlier. Devastated by the death of one child and terrified for the safety of her second daughter, the friend (Christine Hill, guest star Annie Corley) briefly recants her line-up identification. Undeterred, Van Buren proceeds with the investigation, compromising the prosecution lead by A.D.A.s McCoy and Borgia, which forces Van Buren to take the stand.
