Synopsis: Double Dhamaal catches up with the quartet of good-for-nothings - Roy (Ritesh Deshmukh), Adi (Arshad Warsi), Manav (Jaaved Jaaferi) and Boman (Aashish Chaudhary) - who are still dreaming of an easy life with minimal effort when they encounter their old arch-enemy: corrupt Inspector Kabir (Sanjay Dutt). Today, however, Kabir is no longer a cop. In fact, he seems to be doing rather well for himself, driving a Mercedes, working out of a plush office and living in a lavish villa. Naturally, the lads are keen to have some of that, so they promptly bribe Kabir into making them his business partners. What they don't realise is that Kabir has a hidden agenda, shared only with his sexy wife Kamini (Mallika Sherawat) and lovely sister, Kiya (Kangana Ranaut). Before long, the two sides are locked into a game of one-upmanship, with loads of cash at stake. But who will have the last laugh?
