"Shark Escape" tells the diving adventure of four girls, Sophie Nélisse, Corinne Foxx, Brianne Tju and Sistine Stallone, who explore a flooded Mayan city. When they go inside, their mood turns from excitement to terror when they discover that the sunken ruins are the hunting grounds of deadly great white sharks. As their oxygen supply gradually decreases, they must find a way out of their water prison in an intricate and claustrophobic underwater cave and strange tunnels.
