In Plain Sight stars Mary McCormack (Private Parts and The West Wing) as Mary Shannon. Her friends and family think she's just a glorified courier, but she's actually a U.S. Marshal, working for the highly secretive Witness Protection Program. Her job is to help relocate federal witnesses. Whether they're career criminals, or just people who had the misfortune to witness a crime, they all share one thing in common - somebody wants them dead. Co-starring Frederick Weller and Lesley Ann Warren.
In the series finale, Mary finds herself caught between her "model" witness and an unexpected family reunion, while radical changes take place around the WITSEC office.
