After the death of her husband, Jalal, in Canada, Dr. Samiha decides to return to Egypt after more than 25 years, accompanied by her children, Sameh and Samah, to recover their inheritance.

Inspired by true history, The Assassins chronicles the rise of Hassan al-Sabbah in 11th-century Persia — the enigmatic founder of the Order of Assassins, who forged a cult of absolute loyalty and terrorised rulers across the Islamic world. Starring Karim Abdel Aziz, the series weaves together politics, faith, betrayal and bloodshed in one of the most visually ambitious and widely debated productions in Arab television history.
