“Marvel’s Agents of S.H.I.E.L.D.” just declassified some major spoilers. ABC released a synopsis for Season 4 of the drama, and it’s clear that some things have changed. After the Season 4 finale, which skipped ahead six months to show Coulson chasing down the rogue Daisy, fans knew that some shockers were on the way. However, it seems almost everything is changing at S.H.I.E.L.D. headquarters. Here’s what you should know about the new episodes:

1. S.H.I.E.L.D. Is Back — The organization is not underground anymore. After destroying the last of Hydra (supposedly), S.H.I.E.L.D. is going public. That doesn’t include Coulson, though. He is still pretending to be dead, so a new director (Jason O’Mara) has to take his place.

2. Coulson Is Enforcing The Sokovia Accords — Coulson may have been Team Cap, but his hero didn’t win in “Captain America: Civil War.” The Sokovia Accords are in full effect and Coulson is tracking down super-powered humans with Mack (Henry Simmons).

3. Daisy vs. The New Director — Mack and Coulson are still searching for Daisy (Chloe Bennet) in Season 4, but they might not be able to protect her when they find her. “With the world believing that Daisy is a dangerous outlaw who has taken down banks and bridges, the new director has no qualms about taking her down for good,” the synopsis teases.

4. Simmons’ New Job — Simmons’ (Elizabeth Henstridge) relationship with Fitz (Iain De Caestecker) has “taken a big step forward,” and she got a promotion to be Special Advisor to the Director in Science and Technology. Not all is well, though. “Fitz, as well as her former team members, finds it hard to confide in or trust her since she’s now the director’s confidant.”

5. Robbie’s Loyalties — The synopsis describes Robbie Reyes/Ghost Rider (Gabriel Luna) as a junkyard mechanic, but no one knows if he is a hero or a villain yet. “Will Robbie be a friend or foe to S.H.I.E.L.D. – as well as the world, itself?” the description asks.

6. Dr. Radcliffe Is Back — Well, this isn’t too surprising since Dr. Holden Radcliffe (John Hannah) was putting together an LMD in the finale. The scientist will return, and Fitz will discover his new invention when Season 4 kicks off.

“Marvel’s Agents of S.H.I.E.L.D.” Season 4 premieres Tuesday, Sept. 20 at 10 p.m. EDT on ABC.
