In a remote country in Africa, a group of scientists and explorers embarks on an expedition to study the impact of a biological experiment that has gone horribly wrong. What began as an attempt to investigate the local wildlife turns into a nightmare when a series of unexpected mutations transform the animals into enormous and aggressive creatures. In the midst of the jungle, a group of mercenaries joins the researchers to try to survive the chaos that has erupted.
The protagonists, made up of a bold geologist, an inexperienced biologist, and an intrepid photographer, must face their greatest fear: a herd of gigantic gorillas that, driven by rage and confusion, devastate everything in their path. As they try to find a way to escape, the bonds between them grow stronger, and internal conflicts arise regarding the responsibility of science towards nature.
Tension escalates as the jungle, once beautiful and vibrant, becomes a hunting ground where every shadow could be deadly. The characters must confront not only the monsters that have emerged from their own ambition but also their personal demons. In a race against time, they must find a way to stop the threat before it's too late, unleashing a confrontation that will change their lives forever.
