Runway 34 is an action thriller based on a true event that is inspired by the unfortunate crash landing of the Jet Airways Doha to Kochi flight 9W 555, a Boeing 737–800 aircraft which had narrowly escaped in August 2015 with many passengers aboard. The story is that of Captain Vikrant Khanna (Ajay Devgn) who was the captain of the flight along with assistant pilot and first officer Tanya Albuquerque (Rakul Preet Singh) who despite facing difficulties due to bad weather and unclear visibility decides to land on the runway 34 at the Cochin International Airport at 5:45 in the morning. A few bad judgments on behalf of the captain and crew could have headed for disaster for which Vikrant undergoes a trial where the prosecution lawyer Narayan Vedant (Amitabh Bachchan) grills and cross-examines him while his defense lawyer Radhika Roy (Angira Dhar) tries to prove him not guilty. Will Vikrant be proved guilty or not forms the crux of this edge-of-the-seat thriller?
