Zameen is based on the December 1999 hijack of the Indian Airlines Airbus to Kandahar and the subsequent release of Masoor Azhar, Omar Sheikh and Mushtaq Zargar in exchange for the passengers.
Colonel Ranvir Singh Ranawat (Ajay Devgan) captures Baba Zaheer (Mukesh Tiwari), the head of Al Tahir, a terrorist organisation fighting for Kashmir. Six months later, four terrorists infiltrate from Pakistan into India with the mission of securing Zaheer's release.
Meanwhile, Additional Commissioner of Police Jai (Abhishek Bachchan) is tracking a gang that traffics arms and his efforts lead him to the terrorists who have entered the country.
Zameen is a fast-paced action flick that bets on the fairly contemporary references of the plot for its kicks. There are numerous mentions of the attack on the Akshardham temple and the Indian Parliament.
In the climax of the movie, the terrorists hijack an aircraft in which Jai’s foster father (played by Pankaj Dheer) is the pilot and Jai’s girlfriend Nandini (Bipasha Basu) is an airhostess.
Now Ranvir and Jai, who had earlier had fallout on a previous operation two years ago, and also led to jai resigning from the army, join hands to foil the terrorists.
Together, they plan and take control on the situation and eliminate the terrorists.
