While driving home in a state of intoxication after celebrating winning a court case, ambitious young Chicago District Attorney Mitch Brockden (Dominic Cooper) is accidentally involved in a fatal hit and run. In an effort to preserve his legal career, he covers it up. Clinton Davis (Samuel L. Jackson), a 55-year-old car mechanic (whose wife and child had been killed in a home invasion by a parolee) is arrested for the murder, and has reported ties to a series of other unexplained crimes. Brockden becomes the prosecutor for the case and ensures that Davis is acquitted for the crime. After another man is mysteriously murdered in a similar manner as previous unsolved cases soon after Davis' release, Brockden and Det. Blake Kanon (Gloria Reuben) suspect that Davis is a serial killer who murders parolees in an attempt to prevent them committing further crimes.
