Benson and Stabler arrive at McDonald's knockoff "Happiburger," where a suspect and victim are barricaded inside the manager's room. One employee is unaccounted for, a Trini Martinez, and the perp says he'll only open the door for a Detective Milgram (but there's no such detective on the force). They knock on the door, and Olivia says she's Det. Milgram's partner. The door's opened by Scott Adsit, who's relieved to see the cops, and says he did everything Det. Milgram told him to, which apparently is tie Trini Martinez (naked except for a Happiburger uniform) to a chair and stuff a towel in her mouth.

At the station, Elliot questions the guy, Dwight Lomax (who's HappiBurger's manager), keeping up the charade that Det. Milgram is on his way. Lomax says he got a call from Milgram saying Martinez stole a wallet from a customer, who was down at the precinct filing charges, and that means Lomax (who appears to have gotten stupider since he left The Girlie Show) strip-searched her and patted her down. After all, Lomax said he was acting as an agent of the police. Which still doesn't make any sense, or maybe Lomax has a really scary view of how the police force operates. Meanwhile, Olivia's interviewing Trini, who's understandably squicked out about being patted down by her boss, and says she didn't steal anything. "I begged him to stop, but he didn't."

Lomax told Milgram he didn't find anything, and Milgram told him he must have missed something, and that he'd be over. "Took you guys thirty minutes," says Lomax. "You strip-searched a teenage girl and kept her naked in your office for thirty minutes," says Elliot. "You're an idiot." Lomax takes exception to that, after all he's done for the police department. Elliot: "You sexually abused a girl because a voice on the phone told you to." He breaks the news that there is no Detective Milgram. "Oh my god," says Lomax.

As Lomax is brought over to the holding cell, Munch helpfully reminds everyone that "just following orders" is every war criminals favorite defense. Not that he blames Lomax; that's corporate America's fault, apparently, where a franchisee has to conform or lose his Happiburger.

So the detectives want to find Milgram, and Munch points out that Stanley Milgram was a psychologist who performed a groundbreaking experiment involving test subjects administering electroshocks (or at least they thought they did) to other people, to examine the Nazi "just following orders" idea. This seems like much more useful and relevant information for Munch to pass on than his usual tin-hat conspiracy stuff, if you ask me.
