While Agents of S.H.I.E.L.D.’s season finale is tonight, Marvel has released synopses for it’s third season and Agent Carter’s second season. The synopsis for Agents of S.H.I.E.L.D. is fairly vague so you don’t have to worry about much in terms of spoilers.
For Agents of S.H.I.E.L.D.’s third season, it reads:
“Director Phil Coulson (Clark Gregg) embarks on a deadly new secret mission to protect the world from new threats in the wake of SHIELD’s wars with Hydra and a rogue faction of Inhumans.”
As for Agent Carter’s second season it seems she will have a new location and a new cast of characters:
“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.”
