An inmate serving time for vehicular homicide, overhears prison guards discussing plans for a murder and becomes a target himself.

In this thriller, Rob Lowe is a prison inmate who hears more than he was meant to when the convict in the next cell is murdered. The inmate discovers that the murder is just one of a series of killings meant to thin out the inmate population, with the guards working in collusion with members of a victims' rights group seeking their own brand of justice against criminals who escape the death penalty. Proximity also stars James Coburn, Fred Ward, and Jonathan Banks; it was the first feature from Zinc Pictures, a company formed by noted producer Joel Silver to produce quality low-budget films. ~ Mark Deming, All Movie Guide.
