In 2003, a Pakistani Archaeologist Dr. M. Alam Siddiqui after seeking permission from the Government of Pakistan starts researching about the hidden treasure of King Kanishka whose treasure map is hidden in an old box whose key is a Garuda Locket which was last seen in the research books of David, a British Archaeologist. His team led by Siddiqui and Thilavar try hard to search the key as they find the box in an old market in Pakistan.
Fate takes a reverse turn as a dreaded terrorist Sultan (Shakti Kapoor) along with his men visit the Archaeology department. He coerces Siddiqui and takes the box away from him and make all the people his slaves till Siddiqui finds the treasure and hands over it to Sultan.
The story shifts to 2013 in Hyderabad, India. Gautham Kumar Varma (Gopichand) is a poor, brave and money-greedy security guard who wants to make easy money and settle in life. His motto is that he would not take even a crore if it’s not his, but would never let go even a penny if it is his. Gautham Kumar spends his time in testing his fortune by buying lottery tickets and using gadgets which bring luck but sadly both end up giving nothing to him. His friends who are four kids live along with him in the slum colony. Once they ask him to show a 1000 rupee note out of curiosity to which Gautham Kumar agrees. The next day the ATM’s cash cartridge is being refilled and Gautham Kumar requests the officials to show a 1000 rupee note to the kids. They accept and show a note. Meanwhile, a gang of thieves come and rob the ATM. Gautham Kumar catches the criminals and handovers the money. But however since the CCTV footage shows that Gautham Kumar’s request was the reason for it, he is posted to a dumping yard where he would work for nearly 12 hours.
The night he returned from his duty, a heavy rain drenches the colony and the roof in his room fall down. From the roof, he finds a Diary, an old empty bag on which “Pushkalavathi Jewelers, Peshawar” is printed, a Garuda locket, two magnifying lenses and a small stone with a design. He opens the diary and starts reading which is narrated by his grandfather Satyanarayana Varma (Suman). On the day of India-Pakistan, partition activists were attacking rich men and were looting them. After finding no resort to hiding, Satyanarayana Varma packs all his Jewelry and Diamonds and rushes out to a cave which is rumored to be a king’s escape runway. After reaching the spot, he rests at a place keeping his bag on a door of an inlet. A bag with Diamonds falls into one of the Birds attached thus opening the inlet and the bags entering the inner space. He tried hard to get it back but removes the bird from there and falls in an abyss. But however he survived. Now there was a promissory note that 900 Diamonds of his would be inherited by his Grand Son. Gautham Kumar sets to Pakistan with the help of Sreenidhi (Taapsee Pannu), an ardent Hindu devotee who wishes to visit the Hinglaj Mata temple in Pakistan.
There Gautham Kumar and Sreenidhi along with Indian Security contractor Khayamat Raju (Ali) reach the Hinglaj Mata Temple. There he finds his grandfather’s name on a slab and also comes to know by two dwellers that Archaeologists searched about this person. He goes to the Archaeology Department where Thilavar is the new in charge after the brutal murder of Siddiqui and shows the empty bag to them and finds that the address would be in Peshawar. Meanwhile, Gautham Kumar sees the Garuda Locket sketch on the research papers and shows the locket to them. Thilavar offers him money, gold and many things in return for this locket as per Sultan’s orders but Gautham Kumar neither accepts to take any one or all of them nor accepts to give away the locket with respect to his motto. He escapes from them and along with Sreenidhi and Khayamat Raju he goes away to a safe place. Meanwhile, Sreenidhi is made a prey to a Buzkashi game with a rule that the one who parks her in the goal would marry her. A masked Gautham Kumar joins them and after a stiff competition, he wins the match by parking her thus making her fall for him. They move to Peshawar to a local hospital where they join Khayamat Raju with fake injuries and rest there that night.
