Synopsis :
Dum is the story of a young man with strong principles.

Uday Shinde (Vivek Oberoi) is driven by fierce determination to become a police officer and cleanse the corrupt system that clogs the wheels of a civil society.

In his endeavor, Uday walks the less trodden path that is strewn with hurdles galore. His senior officers try to buckle him and subjugate him to the status of a mere minion, but to no use. Particularly, there is the psychotic cop Shankar (Atul Kulkarni) who keeps rubbing the young guy in a wrong way. But Uday gives him back in spades.

However, there are some cops who share Uday’s morality and determination to uphold the law.

For one, there is Mohan (Sushant Singh) who admires Uday’s mettle and befriends him.

Then there is Raj Dutt Sharma (Mukesh Rishi), a quiet cop who believes more in ‘action’ rather than words.

Besides these cops there is also another beautiful admirer of Uday. She is Kaveri (Diya Mirza), a TV host. Deep inside Kaveri loves Uday but he keeps rebuffing her advances in the beginning. However, he grows a soft corner for her with time.

Uday’s unflagging honesty soon wins him many enemies. Besides Shankar, there is a corrupt politician Deshmukh (Govind Namdeo) who uses his power and influence to tame Uday. But Uday is invincible.

The battle between Uday and his enemies hots up until it becomes a matter of life and death for both the parties. Who will prevail – Uday or his oppressors?
