Sanju (Aadar Jain) and Bindya (Anya Singh) are undertrial prisoners and fighting for their justice since three years. Jail supervisor Dhulia (Sachin Pilgaonkar) announces a cultural program to be held on August 15th for which he needs to audition singers and music composers amongst the prisoners. Sanju and Bindya, along with four others, Rufi, Ogu, Maskeen, Tatyana and Sange, form a band named Sainani. Their first song ‘I am India’ becomes an online sensation overnight and their band becomes widely popular.
Things go for a toss when Sanju along with Bindya and other band members plan to escape from the jail to perform in the biggest rock band competition.
