Ed Deline tells Danny McCoy that Detective Luis Perez has been killed in Iraq, informs his loved ones together and tries to correct one of his cases, probably a miscarriage of justice against Richie Betts. Mike must help casino guest Mertens to a whore just before his wife's arrival, so he takes him to Kitty ranch, then is sent back to retrieve his wedding ring, in vain, then must try to get a replica stat. Mary Connell must testify in court against Johnny Moya; the County prosecuting officer turns out to be her romantic admirer Jake Porter; they find a way to spare Moya a strike three life-term. Porter helps Danny to crucial evidence.

Ed Deline is in no position to follow Dr. Hall's advice to take it easy on account of his blood pressure: he's the victim of identity theft, and his banker allowed the culprit to clean him out completely. Danny comes along trying to moderate the punches, but Lou Mosley is just a decoy, the actual brain makes them think again. Sam is hostile to Monica's new non-gambling income watchdog, and even worse to her half-brother Bobby, but her assumption he's still an immature parasite is challenged while colleagues milk him for embarrassing anecdotes. Mike borrows Ed's beloved Aston Martin for an all too adventurous date, which only Ed's name saves from turning into a disaster.
