Detective Ryan Lopez is an up-and-coming Los Angeles Gang Task Force detective. What nobody is aware of is that long ago Ryan once pledged allegiance to a powerful Latino gang known as the Los Angelicos.

Despite Ryan's dedication to his job, he still maintains a sense of loyalty to the gang's leader, Javier, who was also a father figure to him growing up. Javier also masterminded Ryan's entry into the police force.

But now Ryan realizes that his dedication to the Los Angelicos is not what it once was. When Ryan's best friend and partner on the force is murdered by a notorious gang member, he teams up with longtime Task Force member Cassius Green, who has been a vocal leader in the city's war on organized crime.

Ryan, together with Cassius and the rest of the police unit, now works to take down the city's most dangerous gangs.
