What would you do if you were swallowed alive by a whale with only an hour of air remaining? That is the terrifying premise behind Whalefall, the upcoming survival thriller based on the bestselling novel by Daniel Kraus. The newly released trailer follows scuba diver Jay Gardiner as a search for his late father’s remains turns into an unimaginable fight for survival after he is dragged into the mouth of a massive sperm whale and trapped inside its body.
