Plot
Sergeant Joe Gavilan is a financially strapped homicide detective with the Hollywood Division of the LAPD. He has been moonlighting as a real estate agent for seven years. His current partner is K.C. Calden, a much younger detective who teaches yoga on the side and wants to be an actor.
The partners are investigating the murders of the four members of rap group "H2OClick", who were gunned down in a nightclub by two unidentified assailants. The detectives discover there was a witness who fled, and they work to track him down. They are distracted, failing to bond as partners, as Gavilan has to deal with a looming real estate deal that may be the key to getting out of debt, while Calden further pursues his dreams of acting by trying to be scouted by talent agents.
Meanwhile, the manager of H2OClick, Antoine Sartain, has his head of security eliminate the two hitmen, whom he had hired to kill H2OClick, and earlier a rapper named Klepto that Sartain also managed.
Gavilan and Calden believe the murders are gang-related, but when Calden happens to see the bodies of the hitmen at the morgue, they conclude that the murders were orchestrated. The detectives also notice similarities that tie the H2OClick and Klepto homicides together. Gavilan learns from an undercover officer that the songwriter for H2OClick, a man named K-Ro, has gone missing, leading Gavilan to believe he is their murder witness. They struggle to track him down until they finally learn his real name, Oliver Robideaux, the son of former Motown singer Olivia Robideaux.
Meanwhile, Internal Affairs Lieutenant Bernard "Bennie" Macko arrives at the station. Macko and Gavilan have a bad history, as Gavilan embarrassed Macko after proving him wrong on a case years ago. The animosity is compounded by the fact that Gavilan's latest love interest, a psychic named Ruby, used to date Macko.
Macko is intent on ruining Gavilan, going so far as to try to frame him and place both detectives in interrogation. Instead, it only serves to help Gavilan and Calden strengthen their partnership. Gavilan offers to help Calden with the case of his father's death; Officer Danny Calden had been gunned down during a sting operation gone wrong, with his partner, Officer Leroy Wasley, being implicated but eventually released due to lack of evidence.
The partners track down K-Ro to his home, where Olivia professes her son's innocence and that manager Sartain was the real culprit. Sartain had been embezzling money from Klepto, H2OClick and other clients for years. Klepto and H2OClick discovered this and threatened to hire lawyers to nullify their contracts, which led Sartain to have his head of security hire the hitmen as a "lesson" to all his clients. Wasley is not only Sartain's security chief, but Macko is also in league with him.
When the partners cannot locate Sartain and Wasley, Gavilan enlists Ruby's help. She uses her psychic power to lead the two detectives to a clothing store. Just then, Sartain and Wasley happened to drive by, so Gavilan and Calden follow in a wild car chase. It ends with the four men on foot, with two separate chases.
In a struggle with Gavilan, Sartain ends up falling from the top of a building to his death. Wasley draws a gun on Calden and loudly brags about having killed his father. Calden utilizes his acting skills to distract and incapacitate Wasley, and reveals he had a tape recorder on the whole time. Gavilan and Calden reunite as LAPD officers swarm the scene. Macko appears and calls for the arrests of the partners, but instead he is arrested for his part in covering up Sartain and Wasley's crimes.
