6-Headed Shark Attack (2018)

Hungry for the succulent human flesh, and with one head more than the already horrific underwater killer in the 5 Headed Shark Attack (2017), a monstrous, starfish-shaped, six-headed great white shark is now patrolling the waters of remote Isla Corazon, off the coast of Mexico. There, William's supposedly serene couples retreat is under attack, as the evolved aquatic predator spreads terror in unexpected places, devouring the utterly unprepared visitors one by one. But, who's behind the mutated eating machine? Will the nightmare ever cease?
