Bangkok-based bike racer, Sameer Singh, falls into debt with Gulshan and flees to the Bahamas to live with his brother, Sagar, and his live-in girlfriend, Mona. But Gulshan catches up with him, allegedly kills his girlfriend, and forcibly abducts Mona.
In order to return the money, Sameer, Sagar and their friend Aarav decide to scour the bottom of the ocean for a 1949 sunken ship, 'Lady in Blue'. This ship contained treasure that was being returned by the British as a goodwill gesture. The trio will soon find that unknown dangers await them and that one of them has a hidden agenda of his own.
