'I am an expert swordsman. And I am skilled in the business of death. I take no pleasure in my skill. Simply, I am good at it.' 1735 – London, Haytham Kenway has been taught to use a sword from the age he was able to hold one. When his family's house is attacked – his father murdered and his sister taken by armed men – Haytham defends his home the only way he can: he kills. With no family, he is taken in by a mysterious tutor who trains him to become a deadly killer. Consumed by his thirst for revenge, Haytham begins a quest for retribution, trusting no one and questioning everything he has ever known. Conspiracy and betrayal surround him as he is drawn into the centuries-old battle between the Assassins and the Templars.
