The Bay plot
Old friends Emma and Lani are invited to visit a remote bay in Thailand with a shark sanctuary. There, they hope to see the magnificent tiger sharks that have made this place their home. In the capable hands of their captain, Mandal, and his rugged bosun, Ruhan, the young women are captivated by the beauty of this secret paradise. When a giant female shark, nicknamed Sheena, gets tangled in the bait chain while ramming the engine in an attempt to escape, the foursome ends up on a life raft and must use all their resources to survive.
