First 'Agent Carter' Clip: Peggy Goes To Work [Updated With Premiere Date]

Like so many of her sexist colleagues, we made the mistake of underestimating Peggy Carter when she first burst onto the scene. We enjoyed her in Captain America: The First Avenger, but assumed we wouldn't see much more of her beyond the occasional flashback. Little did we know that in a few years time, she'd be headlining her very own series.

Said show, Agent Carter, is due to premiere in a few months, and Marvel is now ramping up its marketing efforts. The very first Agent Carter clip sets up the story: Howard Stark (Dominic Cooper) is in danger, and he's sending his pal Peggy (Hayley Atwell) and his butler Jarvis (James D'Arcy) on a mission to clear his name. Watch the Agent Carter clip after the jump.

Update: Marvel has announced the specific premiere dates for Agent Carter and the return of Agents of SHIELD. Find both below as well.

After the debut of this clip Marvel announced that Agent Carter will premiere on ABC Tuesday, January 6 at 9:00 p.m. ET in the US. After the eight episodes of Agent Carter have run, Agents of S.H.I.E.L.D. will return to ABC with all-new episodes Tuesday, March 3 at its regular time, 9:00 p.m. ET, to complete its second season.

Years before Agent Coulson and his S.H.I.E.L.D. team swore to protect those who cannot protect themselves from threats they cannot conceive, there was Agent Peggy Carter (Hayley Atwell, Marvel's "Captain America: The First Avenger," Marvel's "Captain America: The Winter Soldier"), who pledged the same oath but lived in a different time when women weren't recognized as being as smart or as tough as their male counterparts.

But no one should ever underestimate Peggy.

It's 1946 and peace has dealt Peggy a serious blow as she finds herself marginalized when the men return home from fighting abroad. Working for the covert SSR (Strategic Scientific Reserve), Peggy finds herself stuck doing administrative work when she would rather be back out in the field; putting her vast skills into play and taking down the bad guys. But she is also trying to navigate life as a single woman in America, in the wake of losing the love of her life, Steve Rogers – aka Captain America.

When old acquaintance Howard Stark (Dominic Cooper, Marvel's "Captain America: The First Avenger") finds himself being framed for unleashing his deadliest weapons to anyone willing to pony up the cash, he contacts Peggy – the only person he can trust – to track down those responsible, dispose of the weapons and clear his name. He empowers his butler, Edwin Jarvis (James D'Arcy, "Master and Commander: The Far Side of the World"), to be at her beck and call when needed to help assist her as she investigates and tracks down those responsible for releasing these weapons of mass destruction. But Jarvis, who is a creature of habit and sticks to a rigid daily routine, is going to have to make some major life changes if he's going to be able to keep up with Peggy.

If caught going on these secret missions for Stark, Peggy could be targeted as a traitor and spend the rest of her days in prison – or worse. And as she delves deeper into her investigation, she may find that those she works for are not who they seem, and she might even begin to question whether Stark is as innocent as he claims.
