A documentary crew goes missing in the Amazon rainforest while filming cannibal tribes. When their footage is recovered, it unveils the brutalities that unfolded. Cannibalism, exploitation, violence – it's all here. What's more horrifying, though, is the crew's descent into savagery. Were they victims, or did they willingly embrace the darkness? One thing's for sure – this is one hell of a gut-wrenching watch. No wonder the film was banned in several countries: this is a horrifying experience on so many levels.

Time, when reversed, can reveal shocking truths. Irreversible unfolds backwards, exploring a horrific event that takes place in an underground tunnel. A woman is brutally assaulted, and her boyfriend and ex-boyfriend seek vengeance on her attacker. The aftermath? It's messy, ugly, and mind-bending. The film jumps from one scene to the next, retracing the steps leading to the assault. The brutality of human nature is on full display here – and it's not a pretty sight.

Revenge has a name, and it's Jennifer. This film tells the story of a young woman who retreats to a remote cabin to work on her novel. There, she falls victim to a group of men who sexually assault her. Jennifer, however, is not one to be defeated.

Imagine if serial killers filmed their exploits. That's the premise of August Underground's Mordum, a faux-snuff film that follows a group of sadistic murderers as they document their heinous crimes.

It's vile, it's shocking, and it's a horrifying glimpse into the darkest depths of human nature that will linger in the corners of your mind long after the credits rolled.
