Two men, a teenage boy and a woman attempt to climb out of a cave: the woman hangs from a wire and water pours rapidly over her, her head slams into a rock (we hear the sound of her helmet hitting the rock with a crack), the men and the teenage boy below her struggle to stand up as the water hits them, they are unharmed and the woman rappels safely to the ground.
A teenage boy under water struggles to breathe when his oxygen tank runs out; he climbs against the walls of an underwater cave and breathes in pockets of air, he imagines himself dying (we see the image of the teenage boy floating lifeless in the water), he breaks through the surface of the water and pulls himself onto a beach where he collapses.
