Mary McCormack didn't just play a U.S. Marshal; she basically redefined the archetype for basic cable in the late 2000s. If you were watching USA Network during its "Characters Welcome" era, you know exactly what I'm talking about. In Plain Sight TV wasn't your typical procedural where the good guys win and go home to a white picket fence. It was messy. It was loud. It was frequently heartbreaking.
Mary Shannon lived in a world where her mother and sister were constant liabilities, her partner Marshall Mann was her only tether to sanity, and her job involved hiding people who—honestly—weren't always good people. That's the hook that most shows miss. Witness protection isn't just about heroes saving victims; it’s about relocating mobsters, hitmen, and corporate whistleblowers who often bring their old baggage into their new, boring lives in Albuquerque.
The Reality of the WITSEC Life
Most TV shows treat the Witness Protection Program (WITSEC) like a magic trick. You get a new name, a new haircut, and suddenly you’re a librarian in Ohio. In Plain Sight TV showed the friction. It showed the resentment of people forced to leave their entire identities behind because they did one right thing—or one very wrong thing.
The show focused on the Federal Witness Security Program, a real-world operation managed by the U.S. Marshals Service. Since its inception in 1971, WITSEC has protected thousands of witnesses. Interestingly, according to actual Marshals Service data, no witness who followed the rules has ever been killed while under protection. The drama in the show usually stems from witnesses breaking those rules. They call their ex-girlfriend. They look up their old neighborhood on the internet. They can't stop being who they were.
Mary Shannon was the perfect vehicle for this because she was just as broken as her "witsecs." She wasn't some untouchable federal agent. She was a woman dealing with a father who abandoned her, a sister (Brandi) with a substance abuse history, and a mother (Jinx) who was a professional alcoholic. It’s heavy stuff for a Sunday night.
Why the Albuquerque Setting Worked
Location matters. Usually, shows are filmed in Vancouver or Toronto and pretend to be New York or Chicago. In Plain Sight TV leaned hard into its Albuquerque, New Mexico setting. The landscape is harsh, brown, and wide open. It mirrored the isolation of the characters.

You’ve got the Sandia Mountains in the background and that specific high-desert light that makes everything look a little bit more exposed. It wasn't flashy. It didn't have the neon of CSI: Miami or the grit of a Baltimore-based show. It felt like a place where you could actually disappear, which is the whole point of the program.
The Marshall and Mary Dynamic
Let's talk about Marshall Mann. Frederick Weller played him with this weird, intellectual curiosity that perfectly balanced Mary's "shoot first, ask questions later" vibe. Their chemistry wasn't the "will they, won't they" trope that ruins most shows. Well, it was, but it was buried under layers of professional respect and genuine platonic love.
Marshall was the guy who knew the Latin name for every plant and the historical context of every crime. Mary was the one who just wanted to get through the day without her sister getting arrested or her witness getting shot. It worked because they were two halves of a whole. When the show eventually toyed with their romantic potential toward the end of its five-season run, it felt earned rather than forced.
The Guest Stars and One-Off Stories
What really made the show stand out were the episodic characters. You had veterans like Lesley Ann Warren playing Jinx, but the witnesses of the week were the real stars. They weren't just "Victim #1." They were fully realized people.
Take, for example, the episodes involving former mobsters trying to adjust to life as a suburban dad. The psychological toll of that transition is something the show explored better than almost any other crime drama. You have to mourn your own death while you’re still alive. Imagine never being able to tell your new friends about your childhood or your greatest achievements because those things "never happened."

The show also didn't shy away from the bureaucracy. Dealing with Stan McQueen (played by Paul Ben-Victor), their boss, showed the administrative nightmare of moving humans around like chess pieces. It costs money. It requires paperwork. It’s a logistical grind.
How the Show Handled Real-World Stakes
In 2008, when the show premiered, the TV landscape was changing. We were moving away from the "case of the week" and toward serialized storytelling. In Plain Sight TV bridged that gap. Each episode had a self-contained story, but the overarching narrative of Mary’s family trauma and her evolving relationship with the Marshals Service kept people coming back.
The show faced its fair share of hurdles, including a showrunner change after season two that significantly shifted the tone. While some fans felt the later seasons became a bit more "mellow," the core of the show—Mary's refusal to take anyone's nonsense—remained intact.
It’s worth noting that the show was a massive hit for USA Network. At its peak, it was pulling in over 4 million viewers. That’s a number most cable shows today would kill for. It proved that people wanted a female lead who was abrasive, difficult, and brilliant. She didn't have to be "likable" in the traditional sense. She just had to be real.
The Impact of the 2012 Finale
When the show wrapped up in 2012, it didn't go for a massive explosion or a tragic death. It focused on growth. Mary became a mother, which was a character arc many fans were skeptical about. I mean, Mary Shannon with a baby? It sounded like a disaster.

But that was the point. Life is a disaster. You don't have to be perfect to be a protector. The finale, "All's Well That Ends," gave closure to the family dynamics that had been simmering for five years. It allowed Mary to finally find a balance between her duty to the government and her duty to herself.
Is It Still Worth Watching?
Absolutely. If you’re tired of the hyper-stylized crime shows where everyone looks like a supermodel and uses "magic" technology to solve crimes in forty minutes, this is your palette cleanser. It’s grainy. The fashion is very 2010. The humor is dry.
You can find it on various streaming platforms (usually Peacock or Amazon Prime, depending on your region). It holds up because the human emotions—the fear of being found, the struggle of reinventing yourself, the weight of family secrets—don't age.
Key Takeaways for New Viewers
- Don't expect a romance-heavy show. The focus is on the job and the internal family chaos.
- Pay attention to the witnesses. The best writing in the series often happens in the subplots involving the people Mary is protecting.
- Embrace the Albuquerque vibe. The city is as much a character as Mary or Marshall.
- Stick through Season 3. There’s a shift in tone as the show finds its footing under new leadership, but the payoff in Seasons 4 and 5 is worth it.
If you're interested in checking out the series, the best way to start is by looking for the pilot episode, which perfectly establishes Mary's dual life. For those who want to dive deeper into the actual mechanics of the U.S. Marshals, the official U.S. Marshals Service website offers a surprising amount of history on the real WITSEC program, though obviously, they keep the juicy details classified.
Watching In Plain Sight TV today feels like a bit of a time capsule, but its heart is still beating. It’s a reminder that sometimes the hardest person to protect is yourself.

- Look for the Chemistry: Watch the interactions between Mary and Marshall closely; their banter is widely considered some of the best in 2000s television.
