The film 'Ikkis' (Twenty-One) revisits the extraordinary courage of Second Lieutenant Arun Khetarpal, a 21-year-old Param Vir Chakra awardee from the 1971 India-Pakistan war. Khetarpal, a tank commander, is remembered for knocking out 10 Pakistani tanks before succumbing to injuries. The film draws inspiration from his valor, with personal recollections from former IIT Delhi students who knew his brother, highlighting his sacrifice and becoming a symbol of India's pride.
