Inspired by true facts and events from the1971 Indo-Pakistani war, ‘The Ghazi Attack’ is a story redefining the patriotism in a way which was never done before. The story is about an executive naval officer of the Indian Submarine INS Karanj (S21) and his team, who remain underwater for 18 days. The film explores the mysterious circumstances under which PNS Ghazi sank off the coast of Visakhapatnam in 1971. It is an underwater tale of the courage and patriotism of the men aboard the Indian Submarine S-21 who destroyed the Pakistani submarine PNS Ghazi when it ventured into Indian waters to destroy INS Vikrant. According to the Pakistani Navy, PNS Ghazi sank due to explosions caused by itself or the naval mine(s) it laid in the Bay of Bengal. However, the Indian Navy credits the destroyer INS Rajput for sinking PNS Ghazi.
