Mark your calendars, “Marvel’s Agents of S.H.I.E.L.D.” fans! The team’s next mission starts in September. ABC has revealed the premiere date for Season 4, and Coulson and the crew will be returning at a new time.

“Marvel’s Agents of S.H.I.E.L.D.” Season 4 premieres Tuesday, Sept. 20, at 10 p.m. EDT on ABC. The show is sticking to the same night, but it’s moving back an hour. ABC is hoping that moving the established show will bring in viewers to the struggling timeslot.

Viewers are expecting answers when “Agents of S.H.I.E.L.D.” returns. The Season 3 finale ended with a flash-forward that showed plenty of changes. Coulson (Clark Gregg) was no longer director, but he and Mack (Henry Simmons) were hunting down Daisy (Chloe Bennet), who went rogue after Lincoln’s (Luke Mitchell) death. Luckily, a few hints have been dropped about Season 4.

Obviously, fans want to know more about Daisy. Bennet warned that her character wouldn’t see reason any time soon. Lincoln’s sacrifice will have a major impact on her. “I think it makes her more ruthless being so close to what she thought was her own death,” Bennet told Entertainment Weekly. “And then it happening in one of the worst scenarios she could ever think of, which is the person that she loved doing it for her, I think it changes her in a way where she probably will face life with even more ruthlessness.”

Daisy’s rebellious streak isn’t the only problem S.H.I.E.L.D. faces. Dr. Radcliffe (John Hannah) will cause some trouble as well. He was seen making a Life Model Decoy (LMD) in the finale, but new forms of artificial intelligence can often take a turn for the worst (re-watch “Avengers: Age of Ultron” if you need an example). Executive producer Jed Whedon warned that Radcliffe’s innovations will stir quite a bit of controversy.

“Next year, with the advances in technology, we might be asking the question of, ‘If you can have this, do you want it?’ And a little bit of be careful what you wish for,” Whedon told the Hollywood Reporter after the finale.

Inhumans weren’t given much of a choice with their powers, but Radcliffe might make it so anyone can be a little more than ordinary. Will S.H.I.E.L.D. be okay with those experiments? That’ll depend on the director of the organization. Fans will have to tune in to the Sept. 20 premiere to see who will take over for Coulson.
