A young, idealistic police officer is assigned to an elite unit of the Los Angeles Police Department for an intense training period of 24 hours. Eager to prove himself, he is partnered with a seasoned, morally ambiguous detective who aims to show him the harsh realities of street policing and the complexities of justice in the urban landscape. The detective has his own brand of street justice, and his methods challenge the rookie's principles and shake his understanding of right and wrong.

Their day together takes them on a gritty, tension-filled journey through the drug-infested neighborhoods of LA. As the day unfolds, the rookie is subjected to a series of tests that blur the line between legality and corruption. The veteran detective's connections and tactics expose the young officer to the gray areas of law enforcement, forcing him to make a choice between sticking to his ideals and pursuing his ambition within the police force.
