In present-day London, a young woman named Layla Hassan discovers that she is a descendant of a secret society of Assassins. As she investigates her ancestry via the Animus, a high-tech device that allows her to relive the memories of her assassin ancestors, she stumbles upon a conspiracy involving the Templars, a rival secret society with its sights set on world domination.
As Layla delves deeper into her ancestor's memories, spanning from ancient Egypt to the Viking Age, she uncovers a sinister plot that the Templars have been planning for centuries. With the help of a team of Assassins from around the world, including some of history's most iconic figures, including Altaïr Ibn-La'Ahad, Ezio Auditore da Firenze, and Bayek of Siwa, she embarks on a mission to stop the Templars and prevent a catastrophic event that could threaten humanity.
However, as Layla uncovers more about the conspiracy, she realizes that the Assassins may not be as unified as she thought, and she must navigate a complicated web of alliances and betrayals. Along the way, she wrestles with her own identity as an Assassin, and the sacrifices she must make to save the world from the Templars.
