Frank Elliot is a hotshot television reporter who has just returned from an embedded stint in Iraq. He is shot outside the hip bar Lotus, but survives. Briscoe and Green are investigating and it's clear Briscoe isn't fond of the reporter. At first the Detectives think a defense attorney, Barry Boyd, could be the suspect because Elliot exposed him. But he has an alibi, and besides, he says the publicity, even bad, has really helped his business. Boyd also informs them he's representing the families of three soldiers from the 81st battalion who were killed. The families are suing Elliot and his employer because he divulged the battalion's whereabouts on television, making them sitting ducks for the enemy, thus causing the deaths.
