Raag Desh is about the famous Red Fort Trials of three officers of Indian National Army and how it was a significant chapter in Indian independence movement. 40,000 soldiers of British Army surrendered to Japan after its victory over Britain in South East Asia. They end up switching sides and fighting for the INA. After the INA movement dies down and the soldiers surrender, three of them - Shah Nawaz Khan (Kunal Kapoor), Prem Sehgal (Mohit Marwah) and Gurbaksh Dhillon (Amit Sadh) Ã¢â‚¬â€œ are put on trial for treason. The trial takes place in Red Fort, Delhi. How they put up a great defence and attempt to come out of the trials victoriously forms the rest of the film.
