Hindustan Ki Kasam

A mother gives birth to twins. The twins father was an Indian Army officer who died in war. Unfortunately, they are separated at the end of the war when their father was celebrating their recent success in a battle with Pakistan. One of the twins end up in the neighboring Pakistan and is brought up as a Muslim named Tauheed. He was brought up by a terrorist who told him that his mother had died in an attack of Indian army, while the other grows up as a Hindu named Ajay.

Ajay is a novelist. With the ongoing rivalry and hatred between the two countries, both find themselves on the opposite side, and must battle each other. The only way they can unite is by saving the life of the Prime Minister of Pakistan, who himself has become the target of terrorists.
