Chicago P.D. Episode 2.08 Assignment of the Year

After witnessing an explosive spat outside a sex club between his rich client Asher and Asher's wife Layla, Antonio drives Asher to a gas station to pick up some cigarettes. But when he returns to the SUV, Asher's dead from a gunshot to the head and a sack of diamonds is missing. It's a robbery gone sidewise, all on Antonio's off-duty watch. To make matters worse, turns out Asher had international priors for stealing diamonds. This means that, regardless of whether he finds the murderer, Antonio could lose his job and his pension because he worked for a known felon. Voight and Olinsky vow to protect Antonio - and spearhead the investigation.

Antonio ropes Roman into Intelligence in order to capitalize on his knowledge of Asher, then interviews Layla. Without expressing a drip of remorse, she denies any involvement in her husband's murder, despite Antonio's gut feeling that she orchestrated the whole thing. Lindsay finds a connection between Asher and a jittery jeweler named Wells, who later confesses that someone tried to unload Asher's diamonds. Security footage from the store reveals an image of the shady seller, but the footage proves worthless without an accurate ID. Could this guy be someone Layla met at the sex club?

Voight seizes the opportunity and instructs Halstead and Lindsay to pose as a couple and infiltrate the sex club. Once inside, they find a bartender who confirms that the man from the footage is a regular at the club named Terry - the same person Layla mentioned during the fight with Asher the night of his murder. The bartender also leads them to a jeweler who accepted the diamonds, but once Roman and Antonio interview him, he reveals the diamonds as fakes. With Antonio and Roman's urging, the jeweler sets up a meeting with Terry outside the Field Museum - except Terry pushes for an earlier time, leaving Antonio and Roman without backup. Terry pulls a gun when he spots Antonio and the two engage in a fistfight outside the museum. Antonio knocks him cold and they drag Terry into interrogation.

That is where Terry finds out Layla played him: he will take the rap for the murder and do the time, while she keeps the real diamonds. So where's Layla, anyway? Just so happens she asks for Antonio right outside District 21. Cool and in control, she hands Antonio all her records and assures him her only contact with Terry existed in the club. No paper trail, no evidence. Oh - and she cuts Antonio a check for his security services, her last move before leaving for Florida. Looks like she thought of everything.

But when Antonio returns to the office, looks like the Ivory Tower still wants his badge and gun while they launch an internal investigation - until Olinksy (under Voight's instructions) produces folders of reports that prove Antonio worked undercover and used Roman's security company as a front. Lucky for Antonio, the paperwork appears legit; he keeps his job. He holds back his emotions and thanks Olinsky and Voight for their help... but it's clear that no one will talk about this case ever again.
