In Plain Sight is an American drama television series that premiered on the USA Network on June 1, 2008. The series revolves around Mary Shannon (Mary McCormack), a Deputy United States Marshal attached to the Albuquerque, New Mexico office of the Federal Witness Security Program, more commonly known as WITSEC. Shannon must find ways to balance her professional life of protecting witnesses, her professional relationship with her work partner, US Marshal Marshall Mann, and her problematic personal life. The show was filmed on location in Albuquerque. In Plain Sight concluded on May 4, 2012, after five seasons.
 In Plain Sight was originally scheduled to premiere on Thursday, April 24, 2008, but USA Network held the series back when the WGA strike delayed production of the summer series Burn Notice. It instead made its debut on Sunday, June 1, 2008. It was renewed on July 21, 2008, for a second season with a 16-episode run, which began April 19, 2009.
 Then, following creative differences with Executive Producer David Maples, USA Network made the decision to use the season's 15th episode, the first part of a planned two-part season-ender, as the show's season finale. Series creator David Maples and co-producer Paul Stupin subsequently stepped down as executive producers at the end of season two, although they remained as consulting producers, and were replaced by John McNamara.  Todd Williams and Lesley Ann Warren's roles were changed to guest stars, and a retooling of scriptwriting was designed to place greater emphasis on Mary's cases and less on her personal life, while retaining its character-driven storytelling. According to USA executive Jeff Wachtel, the shift in producers also reflects the network's desire that the show remain upbeat rather than overly dark.
 In Plain Sight was renewed for a third season of 16 episodes on August 2, 2009. Although the previously planned 16th episode of season two was set to be the opening episode of season three, the episode was shelved and replaced by a new opening episode, written by new showrunner, John McNamara. The season was later reduced to 13 episodes when McNamara took a leave of absence for medical reasons. In a statement released exclusively to the Futon Critic, the producer of Universal Cable Productions said, "John Romano assumed executive producer responsibilities for the remaining episodes. Given the unexpected change, we decided to end the season at a natural spot—with the surprising cliffhanger of episode 13."
 After the conclusion of season three, USA Network ordered two more seasons of In Plain Sight   The fourth season premiered on May 1, 2011, in its original time slot. The fifth and final season began on March 16, 2012, and consisted of eight episodes. The series finale aired on May 4, 2012.
 Jeff Beal composed the theme song for the series. W. G. Snuffy Walden composed the music for the first season, followed by Tree Adams for the second season. Evan Frankfort, Liz Phair, and Marc Dauer composed the music for the remainder of the series.
