Last week Marvel added the last piece of its 'Agent Carter' puzzle in casting 'Nikita' star Lyndsy Fonseca, and even though we've seen the first footage, ABC has finally unclassified full details of Peggy Carter's retro adventures. Find out what role Howard Stark and Edwin Jarvis have to play in Marvel's 'Agent Carter' with a new full synopsis for the series!

Per Marvel themselves, it seems Dominic Cooper's return as Iron Man's pop Howard Stark won't prove terribly lengthy or pleasant, given that sinister agents have dragged the good Stark name through the mud, forcing Peggy to step in. We also get a sense of just how integral James D'Arcy's Edwin Jarvis will be to Peggy's adventures, despite a major personality clash between the two:

So reads Marvel's official synopsis of 'Agent Carter':

ABC presents its second action packed series from the creative minds at Marvel in “Marvel’s Agent Carter,” inspired by the feature films Marvel’s "Captain America: The First Avenger" and Marvel’s "Captain America: The Winter Soldier," along with the short "Marvel One-Shot: Agent Carter."

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.

Most recently adding ‘Boardwalk Empire”s Shea Whigham in the role of Peggy’s SSR overseer Roger Dooley, Marvel’s ‘Agent Carter’ also features Chad Michael Murray and Whedon favorite Enver Gjokaj as Agents Thompson and Sousa, respectively. Its pilot will be directed by one-shot helmer Louis D’Esposito, with ‘The Winter Soldier”s  Russo brothers helming the second and third episodes, and ‘Captain America”s Joe Johnston likely the fourth.

‘Agent Carter”s eight-episode season won’t debut until early 2015, but in the meantime, what do you think? Does the new synopsis spell trouble on the horizon for the Stark family? Stay tuned for the latest, and tell us what you want to see from Marvel’s ‘Agent Carter’ in the comments!
