In Plain Sight

After being discharged from the hospital with a fresh bullet wound scar, Mary gets right back to work with Marshall. They come across what appears to be video footage of an armed robbery that one of their witnesses used to orchestrate as a mobster in Boston. The witness: Jimmy McCabe. After grilling McCabe, Mary turns her attention to Jimmy's sons who are doing their best to conceal the truth about their dad. Meanwhile, Marshall's presence in gangland is starting to hurt gang-banger Lala's business. But Marshall is looking for the name of Mary's shooter. It's only a matter of time before Lala's proximity to the cops ruins his business, and before Marshall gets in too deep.

Flash-forward to 2010: Mary and Marshall are rehashing this first case when the couple - now on the road to romantic ruin - jeopardizes their identities when Henry comes to realize that the romance has died. There's also a new face at WitSec headquarters. The newly appointed U.S. Marshall in town, Allison Pearson (Allison Janney), doesn't make a very good first impression with Mary. Mary's sister, Brandi (Nichole Hiltz), is struggling to have her tuition check refunded. And Peter even offers to help her financially, but Brandi has plans of her own.

An ATF agent is gunned down when an arms deal goes bad in El Paso, Texas. After awaking from a coma three years later, Wade Guthrie (Mike Doyle) is placed under WitSec protection as a star witness in a federal case.

When Wade breaks free of US Marshal custody in order to see his former girlfriend, Mary and Marshall go into damage control mode and try to pacify an explosive situation. Also, Marshall relies on fate to link himself with a beautiful pharmaceutical saleswoman named Breck. Could this be love or just a flash in the pants?

The FBI and WitSec are working together to protect a whistle-blower and it appears Mary has met her match. Mary and Special Agent Mike Faber (Steven Weber) butt heads when she arrives. She also finds out that Earl Donaldson (Geoffrey Blake) hasn't been told about all of his witness possibilities. When Donaldson finally chooses to enter witness protection, he jeopardizes his family's safety by telling them about his choice in a bugged house. The FBI's money laundering case then turns into a kidnapping investigation.

His fighting days long behind him, Ricky Dumont (Chad Coleman) believes he's still a heavyweight and that Stan is his old trainer. McQueen is burdened with the responsibility of breaking the bad news to Dumont.

Mary and Marshall travel to Providence, RI to observer their witness' trial when Dominic Difazzio (Louis Lombardi) becomes a star witness against his uncle and mob boss, Vincent Difazzio (Roy Costley). Given Difazzio's murderous track record with explosives, he's not one of Mary's favorites. After settling into his new life in New Mexico, Difazzio opens a local fish store and falls in love with a business neighbor named Naomi (Salli Saffioti). The only problem is that he doesn't know how to act around women, having never been on a date. He begs Mary for a little advice, and she grudgingly agrees. Mary says her goodbyes to Raphael (Cristián de la Fuente), only to run into him later when she accompanies Difazzio on his first date. Difazzio's date goes swimmingly and he tells Mary that he thinks he sees wedding bells in his future. But when Marshall and Mary go to Naomi's home to check on the lovebirds, they're surprised to find another man in the picture. Mary is handed the task of disclosing this information to Difazzio, hoping that his reaction isn't explosive.

Thirty-eight years ago, Frank Jergens' (Fred Ward) good side showed itself while he was robbing a bank. During the heist, he turned on the dirty cops who were helping him pull it off. After 38 years in the pen, Jergens is released to Mary and WitSec, but not before making friends and connections on the inside. Mary is very concerned about Frank's friend, Ray (Brian Goodman), who is indebted to two criminals who are eager to collect. And the more that Mary engages with Frank, the more she is reminded of her father. When Frank's friend Ray shows up at his door in dire straits, Frank must decide whether life on the outside is as good as it's cracked up to be. Meanwhile, Mary gets into trouble with WitSec administrators when they find out she's been abusing U.S. Marshal services to track down her sister.

Natalie Vickers (Alexandra Lydon) was once a part of a mortgage scam in Los Angeles, but now she's under Mary and Faber's watch. Seemingly too nonchalant about entering WitSec, Natalie has apparently attracted her accomplice and boyfriend to Albuquerque where they continue to operate real estate fraud and get caught in the process. The sexual tension between Mary and Faber rises, as the two of them work closely to stop Natalie from indulging in her criminal past. When Mary realizes that Natalie is doing it all for love, the boyfriend becomes a target of the FBI. Yet, Faber has another conflict to deal with, his superior officer in charge, Ike Dennis.

Judy Wagrowski (Karina Logue) is not your average accountant. She was once hired to keep track of the earnings in an illegal numbers racket in Pittsburgh, PA. After being raided by the feds, Wagrowski was turned over to WitSec and Mary becomes frustrated while trying to adjust to Judy's condition. Unable to lie and struggling with body language, Judy is given a job as an accountant's assistant while she waits to testify in the federal case. Mary walks a fine line as she instructs Judy to lie about her identity while in witness protection but to tell the truth in the courtroom once she's called upon to testify against her former boss, Larry Silvers (David Barrera).

Stan puts the pressure on the I.C.E. to renew her status, but he finds out that she may be involved in criminal activity.

WitSec receives a homeless but genius man who witnessed a homegrown bomb attempt and called the authorities, saving hundreds of innocent people. Walter Cooper (Esteban Powell) once lived off the streets of Seattle, Washington and consumed the many books at the library he lived in. But now, Mary and Marshall have to clean up this federal witness to that he's a credible witness for the U.S. Attorney's case. After cleaning up, Walter starts a job at a local Albuquerque bookstore where he's anything but receptive to the idea of an alarm clock, schedule, uniform and nametag. When WitSec uses a federal databank to track down a wanted local fugitive on the FBI's top ten list, Walter gets the idea to use the same method to find his birth mother. Adopted at a young age, Marshall and Mary find out where Walter's mother is located but must race against time to reconnect the two after they find out that she's in grave trouble.
