When a sheriff's squad rolls out each day and the deputies begin their shifts, they call in to dispatch, "10-8… We are now in service."

10-8 explores the LA Sheriffs from the front lines – the patrol car – in the course of the officers' shifts, which can range from the mundane to the dangerous, and everything in between.

Rico Amonte was brought out to LA by his older brother Angelo, a detective in the LAPD Robbery/Homicide Division. He is now in his first year, learning to become a professional police officer, and it's up to Senior Deputy Barnes to teach him the ropes. Their vastly different backgrounds give them opposing points of view on how to police the streets. Amonte's irreverent style can get the job done, but usually not in the way Barnes would call standard procedure.

The other training officers are Senior Deputy Matt Jablonski and Senior Deputy Ryan Layne. Jablonski is partnered with Trainee Gabriella Lopez, a young Latina from East LA. Layne's partner is Trainee Chase Williams, a recent law school grad eager to acquire street experience before he becomes a D.A.

Captain Otis Briggs fights to keep his station running smoothly and by the book. In Los Angeles County, which has the largest sheriff's jurisdiction in the country, it's a daunting task.
