Laal Rang is the story about an ambitious youngster Rajesh who looks up to the notorious local don, Shankar, for life advice and direction. Rajesh (Akshay Oberoi) is a youngster who is in love with a fellow student Poonam(Piaa Bajpai). Rajesh meets Shankar(Randeep Hooda) who runs an illegal blood bank. Shankar also has had a heartbreak through a Punjabi girl (Meenakshi Dixit) whom he still misses.

Though initially, Rajesh is not aware of Shankar's illegal trades, he likes it the instant he comes to know about it and gets involved in earning quick money to impress Poonam. Slowly as the business kicks off, Rajesh starts showing off his money to Poonam. Poonam who is greedy incites Rajesh to get more and this brings friction between Rajesh and Shankar.The cops who have got the hint of this business is also closing in on the illegal activity led by the Superintendent of police (RajnieshDuggall).As things start to fall apart Rajesh starts to play the victim card in front of Poonam. In the end, Shankar declares his crime to the police and gets arrested, saving Rajesh and Poonam's relation.

Five years later, Shankar is finally released from the prison and he reunites with Rajesh and Poonam. The couple had a son who was named Shankar.

The best thing about the film is its novel idea. Although, Laal Rang is half-baked and unconvincing. Laal Rang doesn’t delve deep into the criminals’ modus-operandi, but the two leads try their best to make up for the lack of the nitty-gritty’s. Nobody could have played Shankar better than Randeep Hooda in this film.
