In the aftermath of a riot, cops are being lured into ambush shootings by a rash of bogus 911 calls. Surprisingly Mackey and Captain Aceveda must work together to stop these attacks and solve the problems in The Grove, while Assistant Chief Gilroy tries to pit the two against each other to save his own job.
The Shield breaks the conventional formula of the cop genre. It plays out in a tough, morally ambiguous world in which the line between good and bad is crossed ever day. The series focuses on the tension between a group of corrupt but effective cops and a captain torn between bringing them down and advancing his own political ambitions.
The Shield stars rogue cop "Det. Vic Mackey", leader of the elite Strike Team unit, who is effective at eliminating crime but who operates under his own set of rules. "Captain David Aceveda", the young precinct head who doesn't like Mackey's tactics and wants to bust him off the force. And "Det. Claudette Wyms", a veteran detective who understands Mackey and knows how to play both sides of the fence.
