About Citadel
Citadel from 2023 stars Richard Madden and Priyanka Chopra as agents whose memories were wiped when the agency fell. The six episode first season sets up Citadel against the rival Manticore group and ends with the agency still scattered.
Citadel: Diana from 2024 follows an undercover agent in Milan across six episodes, while Citadel: Honey Bunny from 2024 follows a stuntwoman and spy in India across six episodes. Both run parallel to the main timeline. A second US season has been ordered and filmed with a release expected after 2025, so treat the story as paused rather than closed.
Good to know
Watch the US first season before either spinoff. Diana and Honey Bunny each stand alone as local stories, but their final episodes tie back to Manticore plans that only make sense after the main fall. Diana and Honey Bunny can be watched in either order between themselves. The second US season has no firm premiere date as of September 2026, so it sits outside the released list for now.
