Investigating the highly suspicious death of the person suspected of ambushing three of his fellow homicide detectives, Bayliss (Kyle Secor) runs up against a wall of departmental silence. Meanwhile, wounded detective Felton (Daniel Baldwin) returns to work, though he hasn't recovered emotionally from his ordeal -- nor is he prepared for the hostility attending his return. Pembleton (Andre Braugher) and Lewis (Clark Johnson) have a falling out during the seemingly random killing of a white woman in a black neighborhood. And Munch (Richard Belzer) discovers that he has been used as the "model" for a painting hanging in an art gallery exhibit. Chris Noth makes a cameo appearance in his Law & Order role as Detective Mike Logan. ~ Hal Erickson, Rovi
