In Plain Sight, now in its fourth season on USA network, is a crime drama starring Mary McCormack as Mary Shannon, a U.S. Marshal attached to the highly secretive Federal Witness Protection Program (WITSEC).
Based in the greater Albuquerque/Santa Fe area, Mary Shannon is the ultimate protector. For some witnesses, WITSEC signals a fresh start, but for others it means leaving behind everything they hold dear. In relocating federal witnesses, Mary must protect not only the innocent, but also some of the world's most nefarious criminals and gangsters. For better or worse, testimony guarantees a witnesses' safety at the cost of their previous life. Regardless of their history, Mary helps each of her witnesses stay alive by smoothly transitioning them into their new identities. After all, there's only thing that every federal witness shares in common: someone wants them dead.
Luckily for Mary, she never has to work alone. No matter the situation, her partner Marshall Mann (Fred Weller), always has her back. Despite their significant differences in personality, the two not only make the perfect team, but also the best of friends. The only thing they enjoy more than teasing each other, is teasing their boss, Stan McQueen (Paul Ben-Victor).
Although it's never easy leading the life of a WITSEC inspector, Mary's family has always forced her to take on double duty. While in the past, calling them dysfunctional would be an understatement, things are starting to change for the better. For the first time in recent memory, Mary no longer shares her home with her mother and sister. Gone are the days of alcoholism and meth-filled suitcases. Both Brandi (Nichole Hiltz) and Jinx (Lesley Anne Warren) are gainfully employed, and what's more, Brandi's relationship with Peter Alpert (Josh Malina) is going better than ever. While history tells us that all good things must come to an end, until they do, Mary must learn to interact with a family that no longer needs her protection.
