Four friends — Deshbandhu Roy, Aditya "Adi" Shrivastav, his autistic brother Manav Shrivastav, and Boman Contractor — end up crashing at a woman’s house after a night of partying. Their carefree streak and unpaid rent earn them a sharp rebuke from the landlady, who kicks them out and tells them to get steady jobs. In a moment of desperation, they hatch a plan to make quick money. Adi pushes Manav to pull off a theft: a painting from the house to sell to the heir of a wealthy late businessman. But fate plays a prank, and Manav accidentally picks up a blank canvas. They turn the mishap into a windfall by selling the blank canvas for Rs. 20,000 to the very son they hoped to dupe, all while the plan to seize the original painting hangs in the air.
What begins as a risky grab soon spirals into a bigger scheme when they go after the original painting, unaware that Aggarwal has already been murdered. Inspector Kulkarni steps into the case and pieces together a strange clue: before Aggarwal’s murder, someone called with the code > "Horse ate all the grass". On arrival at Aggarwal’s home, the foursome are nabbed for questioning, but a twist of fate comes when Kulkarni has them released, deeming them innocent after a brief scare on a highway. The group basks briefly in relief, only to cross paths with a dying driver named Don Bose, who reveals a red-hot secret: Rs. 10 crores are hidden in the St. Sebastian garden in Goa, buried under a big 'W'. Bose gasps out a plan to divide the money among the four and then dies. Enter Kabir Nayak, a relentless police officer who has spent a decade chasing Bose, and who arrives hell-bent on extracting answers from the quartet. He doesn’t get them, and the foursome manage to slip away.
In their scramble for the treasure, the four steal Nari’s car, but not before they accidentally strike Nari on the head, knocking him unconscious. A chaotic forest drive follows, with Roy losing control and crashing after a near-miss with an animal. The next day, Kabir is reassigned to Yavatmal after failing to capture Bose, and he returns to confront the four by flaunting photos of Boman’s car and its owner. The foursome stumble into a broken bridge in the forest and, with Boman reluctant to test a risky jump, somehow manage to survive a desperate dare and a perilous explosion. Kabir narrows in on their location, tying them to a tree and pressing for information, but the four break free and make a run for it.
Seeking shelter, they head to a roadside dhaba and pose as investigators, spinning a yarn about Pasha, a feared gang leader, to bait the locals and draw Kabir into a trap. A tense stand-off erupts, and a settlement is proposed: 60% of the treasure goes to the four, while 40% would go to Kabir if he captures the others. Adi, protective of his and Manav’s portion, insists on keeping their money in separate shares when they had planned to pool Boman’s share as one. That disagreement kicks off a new round of brawling, and the four diverge toward Goa, each side determined to reach the goal first.
Their separate journeys to Goa lead to a string of misadventures. Boman reconnects with his father, Nari Contractor, who initially wants revenge for the wrecked car but soon shifts his stance when the potential ten-crore windfall becomes obvious. A private pilot proves unhelpful, succumbing to alcoholism as airline support figure D. K. Malik pushes them to the brink of madness, failing to rescue Bose’s fortune from vanishing. They cross paths with Iyer, a comically persistent man who stretches his patronymic name with every introduction, delaying their progress but adding humor to the trek. Roy strikes a uneasy pact with a dacoit named Babu Bhai, agreeing to share the loot if they can reach Goa together. Kabir himself teeters on the edge of danger, nearly plummeting off a cliff while saving a schoolchild and finding himself entangled in a charity performance for the sake of the community.
When the four finally converge on the garden that holds the treasure, they discover the palm trees arranged in a shape that resembles a big 'W'. Kabir arrives to insist on a fair split, and a consensus seems within reach. They prepare to dig, hoping the long voyage and the near-misses will culminate in a clean haul. Yet old habits die hard, and the dispute over who gets what erupts once more. Adi and Manav want to treat their share as a single unit, while the others insist on separate shares, and in the ensuing chaos Kabir makes a swift exit with the money.
The chase culminates at a charity auction, where the city’s officials publicly commend Kabir for turning the windfall toward a noble cause, a twist that leaves the four friends—and Kabir—facing the consequences of their choices. The film folds into a finale that blends comic caper energy with a raspy moral about luck, loyalty, and the price of chasing a fortune that may slip away just as quickly as it appears.
