A pair of corrupt police officers discover the hard way that crime really doesn't pay in this action drama. Divinci (James Belushi) and Rodriguez (Tupac Shakur) are two New York undercover cops with serious money problems: Rodriguez owes a huge gambling debt, while Divinci wants to retire to Hawaii but lacks the cash.
To stretch their paychecks, the partners pose as drug dealers, using narcotics confiscated as evidence; they sell the dope, and after receiving payment, they kill the buyers in carefully arranged drive-by shootings, always collecting the drugs afterward so that they can be sold again.
The men try to morally justify their actions by claiming that they only kill people who need to be taken off the street anyway.
Divinci's girlfriend, an exotic dancer named Cynthia (Lela Rochon), helps set the cops up with their latest victim, but after they've made the transaction, Divinci and Rodriguez discover the tables have been turned -- the purchaser is actually an undercover DEA agent.
The DEA man winds up dead, and Divinci and Rodriguez are assigned to investigate the killing. Needing a fall guy, they try to frame a homeless man for the murder, but before long, their web of deception begins to collapse like a house of cards.
Gang Related was the final film completed by rapper-turned-actor Tupac Shakur; he himself was the victim of a still-unsolved shooting in Las Vegas 13 months before the film was released.
