Two young IT professionals enjoy a glamorous, gadget-filled urban life. Behind the gloss, they run online shopping scams, buying genuine laptops with fake identities, swapping in counterfeit components, and returning them for refunds. They also resell the authentic parts to keep the profits flowing.

One manipulated laptop reaches Deputy Commissioner Chakravarthi and explodes, triggering an official investigation into the scam. Chakravarthi traces the purchase and narrows the suspect pool to Siddharth and Kallis. The explosion marks the moment their criminal world begins to collide with law enforcement.

Realizing the net is tightening, Siddharth and Kallis fear capture and begin considering safer, more direct thefts. The idea of moving from fraud to car theft is pitched as a means to stay ahead of investigators. Their mindset shifts from meticulous online scams to a more hands-on crime.

Meera's bag is stolen, leaving her frustrated and out of pocket. Siddharth feels a twinge of guilt and convinces Kallis they should mend their ways. They pack their money and move with their girlfriends to Goa to start a fresh business, a restaurant and a beauty parlor.

Chakravarthi tracks them to Goa and storms their house. He discovers that Meera and Shreya have fled with new identities and are already plotting anew elsewhere. The DCP realizes the two women are pulling the strings behind the scams.

Siddharth and Kallis learn Meera and Shreya are in Delhi with fresh identities and preparing another scam. The confrontation reveals they are willing to fight for their own survival and profits. The chase intensifies as all four tail each other across cities.

Meera and Shreya reveal their new names: Madhu and Varsha. Siddharth and Kallis propose a dangerous alliance to rob Sooraj Mehta for ₹80,000,000, promising to split the loot if the partners stay together or split apart if they don't.

Madhu, under the alias Ishita, befriends Mehta through his yoga class, while Varsha ingratiates herself with his wife. The pair opens doors for the crew to move through Mehta's household with plausibly legitimate access. The group steels themselves for a high-stakes heist.

The day of the heist arrives. The team breaks into Mehta's house, hacks Mehta's car with an app Siddharth built, and opens a cash locker with a 3D-printed thumbprint. Madhu stays with Mehta at his guest house by feigning illness, while Varsha keeps watch and the others extract the money.

To dodge Mehta's wrath, the group decides to travel by road to Thailand, avoiding airports and potential surveillance. They map a route that bypasses major checkpoints and plan to disappear abroad.

In the aftermath, Chakravarthi is interrogated by the Central Bureau of Investigation about chasing two minor cheaters. He speaks little, but recalls Madhu's guile as a personal grievance that fuels his determination.

The caravan camps on the road to Thailand, and the film hints that trust among Siddharth, Kallis, Madhu and Varsha remains fragile. The audacious heist sits beside a growing suspicion that alliances may break under pressure.
