Dhamaal is about four friends, Boman Contractor (Aashish Chaudhary), who lives a wealthy lifestyle with his eccentric dad, Nari (Asrani), who loves his antique car more than his son, and asks his son to leave when he damages the car; hot-headed Aditya (Arshad Warsi) and dim-witted Manav (Jaaved Jaffrey), orphaned brothers; and Roy (Ritesh Deshmukh), a trickster who wears a magnetized belt. All four are afflicted by the get-rich-quick virus. Their fortunes take a turn after they accidentally bump into a victim who tells them about a hidden treasure in Goa including 10 crore rupees. The group race toward Goa in Contractor's stolen car, little knowing that their plans will soon be foiled, albeit hilariously, by Police Inspector Kabir Nayak (Sanjay Dutt), who is angered at this Department for not appreciating his honesty, and is instead penalizing him by transferring him to Yavatmal; they all reach there at the same time, and decide it to share it equally. But, Inspector Kabir, at the right time, runs away with all the money. They all follow him and end up in a charity show. They all donate the money to the charity and feel proud for what they did.
