Worn out by the dead-end investigation of the Watson killing, Bayliss (Kyle Secor) turns on the obstreperous Capt. Barnfather (Clayton LeBouef) and calls him a "butthead." As his ex-partner Thormann (Edie Falco) recovers from her wounds, Crosetti (Jon Polito) closes in on the man whom he thinks pulled the trigger -- and who seems eager to confess whether he's guilty or not. While investigating a double murder, Munch (Richard Belzer) becomes fed up with being constantly compared to Bolander's (Ned Beatty) former partner. And Pembleton (Andre Braugher) and Felton (Daniel Baldwin) search for a car that may be crucial to the outcome of a case. ~ Hal Erickson, Rovi
