After nearly three years full of creative overhauls and re-shoots that have seen the budget skyrocket past $250 million, the end is nearly in sight forAnthony and Joe Russo’sCitadelseries at Prime Video.

Touted as a mix between the sci-fi, action, and spy thriller genres, it dives into the crumbled independent spy organization Citadel and the agents who formerly worked for it in a past life. Now, the streamer released the first full trailer today that looks to bring the titular group back from the dead for a new mission with the world on the line.

Much ofCitadelfocuses on Agents Kane (Richard Madden) and Sinh (Priyanka Chopra Jonas), two former members of Citadel whose memories were wiped with the collapse of the organization eight years prior to the events of the series. They barely survived when Manticore destroyed the group from within and are now apart and focusing on their new lives until their former colleague, Bernard Orlick (Stanley Tucci) re-enters the picture. Jogging their memories as hintedin the previous secret teaser, he brings Kane and Sinh back on board for a mission to take down the sinister syndicate Manticore, but in the line of duty, they also begin to rediscover their old relationship and the burning love at the center of all the secrecy.
