What Is the Story About?

Guru is a quick-witted radio jockey in Chennai who secretly hunts for hidden treasures. A failed deal leaves him under severe financial pressure, putting his sister’s family and a close friend in a tough spot.

Desperate for a big payday, he accepts a job to retrieve a hidden ledger belonging to Perumal, a powerful businessman who runs a vast underground network. But the person who hired him betrays him. Perumal seizes his family’s property and holds his close friend hostage, demanding the ledger and a huge sum of money.

The Plan

Guru decides to turn the tables by targeting Perumal’s heavily guarded underground vault, hidden beneath an elite casino. He assembles a team of specialists:

Maya: A clever con artist and expert card player
Master: A veteran safecracker
Dr. Hacker: A technology genius

They plan to infiltrate the casino during a high-profile VIP gala, with Maya distracting Perumal’s chief enforcer at the poker tables while Guru and Master handle the vault’s security. From there, expect a classic heist mix: close calls, a thrilling chase through Chennai and a few smart twists. I won’t spoil how it ends, but a mysterious phone call near the finish hints at another adventure.

Cast and Crew

Sundeep Kishan leads, with Faria Abdullah, Raju Sundaram, Sampath Raj, Shiv Panditt, Anbu Thasan, Yog Japee and Sheela Rajkumar in key roles. Catherine Tresa makes a cameo in a dance number. The film marks Jason Sanjay’s first outing as a director and is backed by Lyca Productions.

Why Watch It?

A heist film is built for streaming: it’s easy to follow, full of twists and perfect for a group watch. With five language options on Netflix, more viewers across India can now check out a debut that drew plenty of attention.
