Locket is the story of a kingdom called Surapur whose old Maharaja entrusted his only grandson Raj Kumar Anil and with his faithful Diwan, and not with his nephew Thakur Veer Pratap as Veer Pratap is greedy and cruel. Maharaja also gave Diwan, a map before his death.

The map leads the way to a treasure containing jewels worth crores. The map was cut in two Lockets. One of which was put around the neck of Raj Kumar Anil and the other around the neck of Shankar. Shankar is the sone of Diwan who as a child witnessed the death of his father at the hands of Thakur Veer Pratap and saw his sister and brother Rajkumar Anil drown in the river.
