Meera’s third birthday is celebrated on the Sea-Bird by the ship’s merchant crew. Drawn away from the party by a sound, Meera is attacked by a ghost and screams. Years later, shipping officer Prithvi Prakashan (Vicky Kaushal), with the help of friend and colleague Riaz, elopes with his pregnant girlfriend Sapna. Prithvi foils a human trafficking operation but Riaz warns him against such dangerous adventures. Prithvi and Sapna have a girl, Megha, and are shown raising her.
Some time later, Prithvi is living alone. He and Riaz investigate the Sea-Bird, which was mysteriously found abandoned at an unmanned port, and recover its logbook. A couple are shown having a romantic adventure on the ship before being killed by a ghost. The body of a girl is found buried on the beach. Prithvi and Riaz attempt to tow the Sea-Bird for disposal, but their salvage ship is damaged. Prithvi is injured saving a drowning man, and sees a girl through a hole in the ship.
While recovering, Prithvi hallucinates of the ship and his wife and daughter. In a flashback, it is revealed that they drowned due to improper safety equipment on a river-rafting vacation he had planned. Disturbed, he consults with Professor Joshi (Ashutosh Rana), who is researching the afterlife and has hallucinations of his own dead wife and daughter. Prithvi returns to the ship and finds a video camera in the engine room; the ghost attacks him but he is saved by Riaz.
