Before Slow Horses, before Reacher, before Homeland made institutional betrayal the norm on our screens, there was Jennifer Garner in a pink wig sprinting through a Taipei nightclub with a stolen hard drive. That image, from the pilot of Alias, is now a quarter-century old, yet its DNA is woven into nearly every spy drama that followed.
Created by J.J. Abrams, Alias ran for five seasons on ABC, blending weekly undercover missions with a sprawling serialized mythology. All 105 episodes recently landed on Pluto TV to celebrate the show's 25th anniversary—just in time for what feels like a Garner renaissance. She returned to The Last Thing He Told Me on Apple TV+ and opened The Five-Star Weekend to a record debut on Peacock. But Alias remains the foundation of her career, and now is the perfect moment to revisit it.
Every Week a New Wig, a New Mission, and a Cast You Won't Believe
If you missed Alias the first time around, here's the setup: Garner plays Sydney Bristow, a grad student who thinks she's working for a black-ops division of the CIA. In the pilot, she discovers the organization is actually a rogue enemy faction, and the series follows her double-agent journey to bring it down from within. Each episode features a new disguise, a new accent, and a new international escapade—Sydney kicks ass and takes names, all while navigating a web of lies.
What truly anchors the show is its toxic family drama. Sydney's father, Jack (Victor Garber), has deceived her her entire life, and the layers of his lies peel back slowly across the first two seasons, reframing everything you thought you knew. Ron Rifkin's Arvin Sloane, Sydney's boss at the fake CIA, shifts allegiances so often that you stop trying to predict him and just marvel at his villainy. The supporting cast is stacked: Michael Vartan, a pre-fame Bradley Cooper, Carl Lumbly, and Kevin Weisman, with guest stars like Quentin Tarantino popping up. There's romance, betrayal, explosions, car chases, mythological undertones, and an identity theft subplot so wild it has to be seen to be believed.
How 'Alias' Rewrote the Spy Drama Playbook
The reason Alias holds up decades later is that Abrams cracked a structural code that became the template for everything after. In 2001, network TV was split between procedural and serialized storytelling. Alias did both simultaneously—each week's mission wasn't filler; it fed you new intel about who Sydney could trust, giving you a reason to tune in every Sunday.
But the show's real innovation was emotional. The missions are fun, but the core is Sydney's fraught relationship with her father. Garner and Garber play off each other with a tension that never fully resolves—she needs him, doesn't trust him, and he loves her but keeps choosing the work. That dynamic is more compelling than any gadget or fight scene, and the genre adopted it wholesale. Homeland's Carrie and Saul run on the same push-and-pull. Slow Horses builds its ensemble around the question of whether your superiors are protecting you or burning you. Reacher circles military loyalty gone wrong. Alias proved that the spy genre's emotional core could thrive on network TV, paving the way for streaming's golden age.
'Alias' Bet Big on Jennifer Garner...and Won
All five seasons are on Pluto, but the first three are where the show is at its absolute best—largely because of Garner. She was 29 when the pilot aired, doing her own stunts, transforming into a new version of the same character every episode, and carrying the emotional weight of a show that demanded everything from her. Sydney could kick through a door and then fall apart in a parking garage ten minutes later; Garner made both feel effortless.
Then there's the Sydney and Vaughn (Vartan) romance. Vaughn is her handler at the real CIA, the one person she can be honest with, and the show takes its time building that relationship. The professional and safety barriers create a tension that runs through the first two seasons, making you impatient for any shift. When it finally happens, it's earned. The Season 2 finale ends on a cliffhanger so disorienting that it resets the entire story for Season 3—one of the boldest swings network TV has ever taken. Everything you thought was settled gets thrown out, and Sydney must figure out what she lost and whether she can get it back.
Seasons 4 and 5 have their moments, introducing new characters and complications that muddy the bigger mission. But the show's early success gave ABC the confidence to let Alias take risks, and even when the story wanes, the ambition never does. For those who want to see where modern spy TV got its blueprint, Alias is essential viewing.
