In Plain Sight - 1 ª Season

During the course of her birthday, US Marshal Mary Shannon tries to find out how a mob hit-man's son under her protection in WITSEC became one of the victims in a double homicide.

Mary protects a 10-year-old witness from being returned to his father, but as the story unfolds learns new information about the boy she's protecting.

Diamond thief, bigamist, and con-artist Teri Ranzino (aka Trudy Wainright, Tenley Bishop, Toni Denard, Tress Stevenson), is put into Witsec after stealing 10 million dollars in raw diamonds from her latest clueless husband/mark, getting arrested by the FBI, agreeing to divulge the whereabouts of 20 million dollars worth of illegal conflict diamonds, and giving up the identities of the men conspiring to sell them. After settling in to her new life, the now-Trenna Morris, finds a new rich man to marry, claims she really loves this one, and ropes Mary into being a bridesmaid. When the diamond smuggler, Ngwama Mubutu, sees her picture in the paper, however, "happily ever after" may not be in her future. Raphael proposes to Mary after being called up to the Majors, with disastrous results.

Horst Vanderhoff, who reportedly works for a high-priced contract killer, gets popped by the F.B.I. negotiating a hit. With promises of delivering the boss, Lola, he goes into Witsec. While transporting Horst, Mary and Marshall are ambushed in the middle of nowhere, Marshall is shot, but they manage to force the would-be killers to retreat. Finding an abandoned building, they take cover and prepare to defend themselves when the assassins return at nightfall to finish the job.

After setting her cheating, art thieving husband up for the F.B.I., Marci and Jay Allen (now Arnstein) are placed into WITSEC, because the art smugglers/fugitives Jay worked with, are still at-large. As retaliation for his wife's betrayal, and as part of his deal with the D.O.J., Jay insists on bring his mistress into the program as well. Unfortunately for him, after six months, he tries to turn over a new leaf by getting Mary to re-relocate his mistress, Kay, moments before she shows up drunk at an art show, exposing Jay's secret to his wife. Shortly afterwards, Jay is critically shot. This begs the question... who shot Jay Arnstein? The scorned wife? The jilted lover? The smugglers? Or could it be some new, unknown threat? While recovering from a sports injury, Raf is laid-up at Mary's where he and her adversarial sister, Brandi, get a chance to know each other better.
