Mark Fuhrman, a former Los Angeles Police Department detective who gained notoriety during the O. J. Simpson's murder trial, is intrigued by the case and travels to Greenwich, Connecticut, to conduct an investigation of his own.

The film alternates between flashbacks of the events leading up to the murder and scenes set in the present day, which chronicle Fuhrman's frustration and interactions with Steve Carroll, the original investigator who grudgingly assists him.

Michael Speier of Variety said, "Investigative techniques give way to genre cliches in USA's exaggerated Murder in Greenwich.

Falling into the telepic trap of sensationalism without savvy, [it] delves into the shallow end of the Martha Moxley-Michael Skakel case, which has plenty more politics, intrigue and confounding history than this execution suggests .

As Fuhrman, Meloni is macho almost to the point of bogus; whether he's playing the disgraced cop as he really is or how he thinks America sees him is hard to discern.
