Belker goes to the dogs working undercover at the pound; Furillo chases down the reason he's been denied mortgage insurance; LaRue and Washington bust a former baseball star for drunken driving; and Buntz is held hostage by a vicious parolee.

Hill, Renko and Buntz look like heroes when they retrieve a stolen heart needed for a transplant; rookie officer Ron Garfield finds himself in trouble again when a second gun shows up at an officer involved shooting; and Belker misses his wedding ceremony when his undercover as a cocaine cooker heats up.
