One man with courage makes a majority. One such man is Uday (Vivek Oberoi). His dream of becoming a police officer and serve his country is accompanied by fierce determination and drive. Even as he courageously treads on his chosen path, he is confronted by the face of evil in the form of a police officer, Shankar (Atul Kulkarni).

Shankar's deviously selfish intentions are almost as strong as Uday's selfless, noble ones. Indeed, just as each coin has two sides, society has two faces - that of the good and evil. Such as that of Uday and Shankar!

A spellbinding narrative of the grit and will power of a common man Uday, Dum reveals his travails as he overcomes all the barriers that come in the way of achieving his goals of fighting the injustice and evil that blackens society.
