Inheriting from our ancestors, the legacy of the Ayurveda panacea 'Vajrakavach', a famed and effective remedy for all ills, the brother duo Pooran and Kaala use the kavach with varied intentions. While Pooran who is good-hearted puts in use his heritage to help people, Kaala looks out for his interest in money. Parmar, an erstwhile Casanova and a colorful character who is also a sharp and intelligent lawyer of repute, is the paying guest in the brothers' house. He is a thorn in Kaala's side, as he is paying the same rent, Rs. 125.00, for the last 35 years. Adding to the Punjabi mix, Chikoo is a pretty Gujarati girl, who steals Kaala's heart and brings a sinister twist to the tale.
