Doing Hard Time (2004)

Synopsis
A man turns to crime in the name of justice in this hard-hitting drama. Michael (Boris Kodjoe) was a good father and a law-abiding citizen until the day his seven-year-old son was accidentally killed in an exchange of gunfire between two gangs of drug dealers. Michael became obsessed with seeing the gunmen brought to justice, but when the murder charges were dropped and the shooters were given a short sentence for drug possession, Michael decided to take matters into his own hands. Michael commits a crime so that he will be placed in the same prison as the men who took his son's life; once there, he can take their lives in exchange for the life they took. But Michael seriously underestimates the ruthlessness of the prison population and must fight for his own survival before he can carry out his plan. Doing Hard Time also stars Giancarlo Esposito, Steven Bauer, and Sticky Fingaz. ~ Mark Deming, All Movie Guide
