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.

The story revolves around a grandfather who stole a rare masterpiece belonging to the late singer (Umm Kulthum) in his youth, but after years passes, he finds himself chased by those who want to have this piece, which makes him resort to the help of his only grandson.
