Ego tells the story of Elif and Erhan, a young couple whose dream of marriage is shattered when Erhan’s failed investment leaves Elif’s family facing the loss of their home. Crushed by debt and guilt, Erhan is driven into accepting a dark offer from his powerful boss, Sibel Koraslan, a woman recently abandoned, devastated by the news that she may never be able to have children, and desperate to become a mother at any cost. Choosing Erhan as the father of her future child, Sibel pulls him into a dangerous deal that destroys Elif’s trust and tears their love apart. As Erhan is drawn deeper into the world of the wealthy Koraslan family and eventually marries Sibel, Elif’s life falls apart. Unemployed and heartbroken, she enters the Koraslan household as a babysitter and becomes entangled in a forbidden relationship, this time with Sibel’s married brother, Tuncay. When Elif’s unexpected pregnancy comes to light, Erhan is forced to face the hardest decision of his life: stay with the woman he loves, or become a father for his future child.
