Citadel, an independent spy agency, is wiped out by Manticore, a powerful syndicate that’s desperate to take charge of the world. Diana, an undercover Citadel agent, works as a mole in Manticore. She forges an unexpected rapport with Edo Zani (the heir of Manticore Italy), who is keen on taking the mantle from his father Ettore, grooming himself to be a capable leader.

Citadel Diana is one of the many spin-offs set around the American Citadel led by Priyanka Chopra. The series explores the world of a covet organisation across the globe trying to take down the world’s most evil organisation Manticore. While Citadel carried the story more straightforward, Citadel vs Manticore, we get to see a different side in Diana. The Italian show led by Matilda De Angelis, Lorenzo Cervasio and Maurizio Lombardi explores more on the side of how things are done at Manticore. Released in Italian, with few dialogues in English, the show is expected to have a stronger opening than Citadel.
