Starring Dileep, Sathyaraj (in his Malayalam debut), Charmy Kaur,Lal and Biju Menon.

During a terrorist attack on the village, Gautham's parents are killed and his older sister drags him away hides behind some trees.

The narrative shifts to the present, where an adult Gautham Menon visits his elderly uncle Dr. Unnithan, a physician who is also his childhood mentor and a friend of his late father.

He visits Major George Joseph, a retired Army officer who was court martialled from his position for arguing with superiors while intoxicated.

Later, he sees his mother trying to call his daughter Shreya, asking her to stop by while en route to Bangalore so that they could proceed with her marriage to an NRI boy.

Coincidentally, Gautham has also rented the house owned by Sudhir's brother and befriends his family, though he tactfully dodges Shreya every time she sees him.

Gautham speaks to the General in private and reveals the truth that his sister was cruelly raped by Varma, who was the commanding officer after killing all the terrorists, knocking her unconscious for the rest of her life.

Varma had asked Major George, who was a silent witness to his cruelty, to report it as a terrorist act thereby hiding the truth.

A large party of the General's ex-colleagues, including Major George, is invited to the function by Gautham using Varma's email id.

Though the General points the gun towards Gautham, he cannot pull himself to shoot him, thereby silently admitting the crime and all the guests turn against him.

Guilt ridden and realizing his mistake, he leaves the scene and commits suicide after writing down the confession to the President of India and returning all the accolades and awards he received during his service.

Vidya Balan was considered to play the female lead even though she was interested in the character couldn't take up due to prior commitments.

Finally Telugu actress Charmy Kaur replaced the latter marking her come back to Malayalam industry after a hiatus of 8 years.
