The first promo for the return of "Marvel's Agent Carter" features the quick wit and action viewers grew to love about the show in its first season. Hayley Atwell, James D'Arcy and Enver Gjokaj's characters head west to the glitz and glamour of post-WWII Hollywood, but while the scenery may have changed, the action and intrigue remain a big part of their lives.

"Marvel's Agent Carter" returns for a second season of adventure and intrigue, starring Hayley Atwell in the titular role of the unstoppable agent for the SSR (Strategic Scientific Reserve). Dedicated to the fight against new Atomic Age threats in the wake of World War II, Peggy must now journey from New York City to Los Angeles for her most dangerous assignment yet. But even as she discovers new friends, a new home - and perhaps even a new love - she's about to find out that the bright lights of the post-war Hollywood mask a more sinister threat to everyone she is sworn to protect.

"Marvel's Agent Carter" returns to ABC on Jan. 5, with a two-hour season premiere.
