Mona is a pretty but reserved young girl who lives with her mother. One day, she meets Magdy, a wealthy businessman and his friend Doctor Fouad. The young woman is attracted to Fouad but her mother prefers that she marry Magdy because it would allow her to definitively get out of her financial difficulties and access the comfort she has always dreamed of. Mona is an obedient girl and becomes Magdy's wife. But she quickly learns that her husband is powerless: a fall from a horse has permanently deprived him of his virility. Gradually, Magdy becomes obsessively jealous and the arguments between the two spouses multiply.
