The film is about falling in love for the first time and the excitements and nightmares associated with it. MP3 brings together two fresh and very talented faces, Ruslaan and Hazel on screen for the first time. Rohan, an egoistic and lazy boy is seeing a pretty and caring girl, Ayesha. Not able to find the love and attention that she seeks, Ayesha breaks up with Rohan and leaves for Paris.
Rohan wants her back badly than ever. Rohan starts to feel the void and decides to go to Paris to meet the love of his life! Hence, Rohan sets off on a journey to Paris alone with no money, visa or a contact number. He dodges and fights whatever stands between him and Ayesha, finally making it up to her.
