The Agents of SHIELD season six finale ended with the Agents realizing that to save the world they must travel back in time to the 1930s. ABC has released a trailer for the seventh and final season of the show, which sets up the time traveling adventure.

The Chronicoms, the extraterrestrial androids that were sent to our galaxy to observe events and served as villains in season six, are back and causing more damage. As if fighting the powerful androids wasn’t enough, the Agents’ mission gets more complicated when they realize that to save SHIELD, they have to save Hydra.

Season seven kicks off on May 27, 2020.
