OM Trailer Out: Dhanush Goes Undercover, Mammootty Plays Deadly Smuggler In Action-Packed Saga

The trailer for OM, starring Dhanush, Mammootty, and Sai Pallavi, has been released.

Dhanush and Mammootty coming together for a film is exciting enough, but their latest trailer has given fans even more reasons to look forward to it! The trailer of OM is finally out, and it promises plenty of action, drama and intense face-offs.

Directed by Rajkumar Periasamy, who has also written the film, OM is inspired by true events. The story is "set between two temple towns" and "torn between two worlds." Dhanush plays an undercover officer from the Tamil Nadu Police Department's Organised Crime Unit Intelligence Unit's D Team. Sai Pallavi plays a police officer, while Mammootty and Naseeruddin Shah appear in powerful roles.

The trailer takes us straight into the world of red sandalwood smuggling. We see Dhanush as a forest worker, but there's more to his character than meets the eye. He is actually an undercover cop who enters the smuggling network to find out who is running the illegal business.

As part of his mission, Dhanush goes undercover as a woodcutter and slowly becomes part of the gang. The trailer shows him working in the forest and trying to win the trust of the people involved in the racket. But things are not easy. There are moments when he is caught between the smugglers and the police, making his mission even more dangerous.

We also get a glimpse of his personal life. Sreeleela plays his wife, who is unhappy about the fact that she and their son have to stay away from the public eye because of his risky job.

And then comes Mammootty! The actor plays Burma Karthikeyan, also known as Siya, a powerful international smuggler. His character appears to be one of the biggest names behind the illegal trade. Naseeruddin Shah is also part of the film, although the trailer doesn't reveal much about his character.

Sai Pallavi, meanwhile, plays IPS officer Nithya Reddy. She was earlier an Assistant Superintendent of Police in Andhra Pradesh before joining the CBI. She leads Operation Mole and works with Interpol to bring down the smuggling network. The trailer shows her taking charge of the investigation as the police get closer to the people running the racket.

There are plenty of action moments too, with Dhanush caught in a dangerous situation as his undercover mission gets more complicated. The trailer builds towards an intense battle between the people involved in the smuggling business and those trying to stop them.

Inspired by real smuggling operations along the Andhra Pradesh-Tamil Nadu border, the film also looks at the exploitation of rural workers and forest labourers. The red sandalwood trade has already reminded some viewers of Allu Arjun's Pushpa, which explored a similar illegal business.

OM - Chapter 1: Udhiram - The Blood Wood is set to release in theatres on November 20, 2026.
