The story begins with the theft of an extremely valuable diamond in Mumbai by a thief named Rocky. He is meant to hand it over to an accomplice of his London-based uncle, Choksi, in Dubai. However, news of the diamond's arrival attracts local gangster Moscow Chikna, who coerces the debt-ridden junk shop owner Chobey into stealing it for him. Chobey enlists the help of his small-time criminal niece, Tina, and her talented boyfriend, Raja. Raja himself is living a double life, paid to impersonate the deceased nephew of an elderly woman named Lajwanti to spare her trauma. The diamond's trail soon draws the attention of more underworld figures: J.D., a powerful don who runs illegal fight rings, and Gunmaster G9, a detective hired to recover the stone. Chobey's group successfully intercepts Rocky, but in a chaotic turn of events, Moscow Chikna kills Rocky and takes the diamond. However, Chobey's quick-thinking group manages to steal the diamond back during the subsequent commotion, only for it to be accidentally swallowed by Chobey's dog, Hajmola, turning the animal into the most valuable creature in Dubai.
Running parallel to the diamond chase is the story of Munna, a man of integrity who runs a garage and is unaware that his elder brother is involved in a car-stealing ring. Munna crosses paths with Lucky, a gambler desperate to repay his debt to Don J.D. by recruiting fighters for his illegal bouts. Munna is dragged into J.D.'s conflict when the don's men burn down his home in India Colony. To protect his community and save his lover, Payal — a girl on the run from J.D.'s human trafficking operation — Munna reluctantly agrees to fight for the gangster.
