chunk: Socialite Claire Gregory (Mimi Rogers) attends a party and art show sponsored by one of her oldest friends, Winn Hockings (Mark Moses). Accompanying her is her straitlaced boyfriend, Neil Steinhart (John Rubinstein). In another part of town, there is another party, this one for newly appointed NYPD detective Mike Keegan (Tom Berenger).
  Winn is accosted by a former partner, Joey Venza (Andreas Katsulas), who is angry because Winn had not come to him to borrow money for his new art studio. After a short argument, he stabs Winn to death. Claire witnesses the killing as she steps out of the elevator; she screams and is spotted by Venza. He pursues her, but she manages to get back into the elevator just in time.
  The police are called in and the new detective Keegan is there. He is a married man, but immediately falls for Claire. Along with fellow cops, he is assigned to protect Claire until she can make a positive ID of Venza (once he is arrested) and testify in court.
