NAACH tells the story of two characters - Rewa [Antra Mali], a wannabe choreographer and Abhi [Abhishek Bachchan], a struggling actor.

Rewa and Abhi are both trying to get a foothold in the industry. Abhi is lucky to get a break, while Rewa is shown the door since the lead actress wants her fav choreographer in the film. Things reach a stage where Abhi and Rewa go separate ways due to ideological differences.

Abhi becomes a big star, while Rewa continues with her struggle. She finally manages the big break when a music company boss, Diwakar [Ritesh Deshmukh], offers her a video, as an actress. There's no looking back, Rewa becomes famous overnight.

Abhi and Rewa meet again, this time in a restaurant. There's uneasiness. The same night, Abhi confesses to Rewa that he still loves her. But Rewa turns down the offer.
