Allaudin (Prabhu Deva) is an illiterate who lives in Allikuppam, where he was abandoned as a child. He grows up in the slums and fights against injustice towards the people with whom he shares a special bond. Allaudin's enemy is Gangadhar (Raghuvaran), a ruthless man.
One day Allaudin finds evidence that Gangadhar had committed a murder and thus he becomes our hero's Magic Lamp, as he starts blackmailing him. Thus the messiah of poor slum dwellers becomes a sort of Robin Hood by satisfying all the needs of the people dear to him. In the meantime, Allaudin falls in love with Gangadhar's employee's daughter (Aashima). And in a gripping climax, Allaudin is shot, a twist in the climax is revealed then.
