Treasure hunt winner announced

To usher in this highly anticipated “Citadel” finale, Prime Video also announced the winner of a multi-platform treasure hunt called “Citadel: Crack the Codes.” The contest, which drew over 30,000 contestants, took place between May 3 and 5, 2023. Ernesto Ramon Amao, a Human Resources officer from Marikina City, took home the P500,000 prize.

Eight years ago, Citadel fell. The independent global spy agency — tasked to uphold the safety and security of all people — was destroyed by operatives of Manticore, a powerful syndicate manipulating the world from the shadows. With Citadel’s fall, elite agents Mason Kane (Richard Madden) and Nadia Sinh (Priyanka Chopra Jonas) had their memories wiped as they narrowly escaped with their lives. They’ve remained hidden ever since, building new lives under new identities, unaware of their pasts. Until one night, when Mason is tracked down by his former Citadel colleague, Bernard Orlick (Stanley Tucci), who desperately needs his help to prevent Manticore from establishing a new world order. Mason seeks out his former partner, Nadia, and the two spies embark on a mission that takes them around the world in an effort to stop Manticore, all while contending with a relationship built on secrets, lies, and a dangerous-yet-undying love.
