In 2012, Desmond Miles, a seemingly ordinary bartender, is kidnapped by Abstergo Industries for use as a test subject in the Animus, a device that can simulate genetic memory. Under this program, Desmond is forced to relive the memories of his Syrian ancestor Alta'ir ibn La-Ahad, a member of the Assassin Brotherhood who lived during the Third Crusade in the Holy Land, struggling to find answers on his situation all the while.
In 1191, seasoned assassin Alta'ir ibn La-Ahad botches an important mission in Jerusalem, leading to countless deaths - and his demotion. To redeem himself, Alta'ir is assigned nine targets across the Holy Land to eliminate. As he progresses throughout his mission, Alta'ir slowly learns of a larger conspiracy that threatens to uproot everything he's known.
