Egypt, 70 BC e. The peaceful village of Siwa, located in the middle of an oasis, knows almost no grief. But one day a messenger arrives here with a mysterious message for the local protector, and he is forced to leave his home, wife and growing son. Tormented by questions that only the father who left Siva can answer, Bayek follows. The young man has no idea that his father and himself are being hunted by a dangerous mercenary, sent by a mysterious order of the ancients to stop the line of “defenders of Egypt” - the Medjays. Thus begins the confrontation between the two orders, which will last for centuries and develop into a real war - the war of the Assassins and Templars.
