A popular New Orleans talk show hostess is slashed and left for dead. Investigator Marsh and his lover, Assistant District Attorney Jacobi, are determined to solve the case in an effort to boost Jacobi's impending promotion. As Marsh digs for clues in the seamy singles bars the victim frequented, Jacobi's instincts pull her towards the home of a respected surgeon who the talk show hostess identified as her attacker when she was brought into the operating room.
