IN PLAIN SIGHT will air its fourth season beginning Sunday, May 1 at 10/9c on USA Network.  IN PLAIN SIGHT stars Mary McCormack as Mary Shannon, a U.S. Marshal working in the highly secretive branch of the witness protection program (WITSEC), who relocates Federal Witnesses, most of whom fall into three categories: career criminals, whistle-blowers or innocents who had the misfortune of witnessing a crime.  They all have one thing in common – someone wants them dead.  Mary’s job is to see that doesn’t happen, while at the same time attempting to manage her own dysfunctional family. In the upcoming season, Marshall will have a new love interest; Brandi gets engaged to Peter, and Mary reluctantly helps plan the wedding!  Visit the official IN PLAIN SIGHT website at http://www.usanetwork.com/series/inplainsight/ for exclusive content and become a fan on Facebook.
