SEX/NUDITY 10 - Two young women are seen swimming underwater fully nude (full-front nudity is seen on both, including genitals, bare buttocks and bare breasts); they swim suggestively while rubbing one another's breasts, as two men watch, film them and make crude remarks and when they get out of the water their bare buttocks are seen in an extreme close-up.
► Two silicone bags (the implication is that they are breast implants torn from a woman's chest) float in water along with severed male genitalia; we see two fish fight over the male organ, and one swallows it and then spits it out (the image of the genitalia, bloody and deformed, fills the screen).

VIOLENCE/GORE 10 - Fish swarm and attack a crowd, tearing off chunks of flesh as they swim through the water: blood fills the water and countless people are injured in an extended sequence showing bodies being ripped apart underwater and people screaming incessantly; injured people are pulled onto boats, blood pours from their large wounds, missing limbs, and limbs eaten down to bone are seen on large numbers of people as blood-covered helpers attempt to pull them to safety. Maimed, blood-covered people are seen being torn apart by fish, and blood and torn flesh fills the water.
