Fishermen talk of a giant beast that hunts the tropical abyss of the Seychelles archipelago. Wily, strong, and tough as nails, the dogtooth tuna is said to be as ferocious as any shark.

But to find out, he'll need to push himself to the limit, free dive deep into a seemingly bottomless abyss, and brave a storm at the start of monsoon season.
