Khalil is a teenage boy, son of a poor porter, and sees him dying when serving a man without compassion. Khalil keeps on with father's work, to pay for his younger brother and their old mother food and shelter in a slum. Then, the horse that pulled the chariot dies, and Khalil goes on, taking the animal's place. A rich man tries to kill another, and pays Khalil to pick up the revolver, and take the blame - going to prison instead of him. Khalil accepts, and takes the money to his mother. In prison, Khalil grows up as a rowdy man. Later, fate will bring the two brothers together, but in opposite sides of the law: Khalil is a paid assassin, and his brother is a public prosecutor. When the Mafia pays Khalil to kill his own brother, he refuses - and the Mafia retaliates by killing his wife. Khalil vows to revenge her.
