Kannum Kannum Kollaiyadithaal 2020

Siddharth and Kallis (Kaliswaran) are two young IT professionals living a seemingly luxurious life, enjoying fast gadgets, sleek laptops, and the glow of a high-end urban world. Their romantic horizons include Meera, a beautician, and Shreya, a chef, who appear to be their girlfriends and partners in a glamorous lifestyle. Beneath the surface, however, both men are con artists who pull off online-shopping scams to line their pockets. They buy genuine laptops using fake identities, swap in counterfeit internal parts, return the devices for refunds, and then sell the real components to keep the money rolling.

One such manipulated laptop ends up in the hands of Prathap Chakravarthi, a Deputy Commissioner of Police (DCP), and it immediately explodes. Chakravarthi traces the purchase and zeroes in on Siddharth and Kallis. Realizing the net is closing in, the two men contemplate shifting from computer scams to straight car theft as a safer, more direct form of theft.

Meanwhile, a thief steals Meera’s bag, leaving her frustrated and out of pocket. Siddharth feels a twinge of guilt and decides they should truly mend their ways. He and Kallis pack up their money and move with their girlfriends to Goa, planning to start a restaurant and a beauty parlor as a fresh business venture and a new life.

Chakravarthi tracks them to Goa and storms their house with police. At first, the men fear they’re the police’s target, but Chakravarthi reveals a startling twist: he’s actually looking for the two women who fled just before his arrival. Siddharth and Kallis realize Meera and Shreya have forged new identities and are continuing their own schemes elsewhere, having used their supposed relationships to prey on their partners.

After some digging, they discover Meera and Shreya are in Delhi, and have prepared for their next scam with new identities. The two women are stunned that Siddharth and Kallis have followed them, and they agree to return the money and force them to part ways. Yet Siddharth proposes a dangerous alliance: they will work together to rob Sooraj Mehta, a wealthy businessman, of ₹80,000,000 (US$950,000). If the women love them enough to stay together, great; if not, they will split the loot and go their separate ways. The women yield and reveal their new names to be Madhu and Varsha.

Madhu adopts a new identity (Ishita) and befriends Mehta during his yoga class, while Varsha befriends his wife. Siddharth and Kaliswaran manage to break into the couple’s house, and in the process, Siddharth discovers that Sooraj is a drug lord. The others feel wary about continuing, but Siddharth convinces them to press on by planning an escape route out of the country after the heist to dodge Mehta’s wrath.

On the day of the heist, Varsha spends the day shopping with Mehta’s wife, and Madhu stays with Mehta at his guest house, while Siddharth and Kaliswaran loot the house. They steal Mehta’s car by hacking it with an app Siddharth built, then use the car to enter Mehta’s compound. Inside, they open a locker with a 3D-printed thumbprint to grab the cash, while Madhu fakes an illness to slip away from Mehta’s house. To avoid drawing attention at the airport, the group decides to travel by road to Thailand.

Back in Chennai, Chakravarthi is questioned by the Central Bureau of Investigation for bending the chase toward two small-time cheaters. He remains mostly tight-lipped, but he candidly recalls being a past victim of Madhu’s guile, which explains his personal stake in chasing her down. The young lovers are shown camping on their way to Thailand, leaving the audience with the sense that trust between them may not be as solid as it seems. The film closes with a lingering hint that, despite the bold heist and their joint scheme, honesty among the group remains fragile and unsettled.
