BEWARE BOIúNA

Beware Boiúna Awakens an Ancient Terror in the Amazon

Something ancient is waiting beneath the waters of the Amazon.

Beware Boiúna is a survival thriller that sends a team of doctors deep into the Amazon rainforest, where a humanitarian medical mission unexpectedly brings them into the territory of a legendary predator.

Traveling along the Curuçá River, the group arrives intending to provide medical assistance to local communities.

But their presence awakens something that doesn't want them there.

The Boiúna.

Drawn from Amazonian and Brazilian Indigenous folklore, the Boiúna is a colossal black serpent associated with the rivers and waterways of the Amazon. Sometimes known as the “Mother of Waters,” legends describe the creature as an enormously powerful ruler of the river capable of capsizing boats, dragging travelers beneath the surface and even changing its appearance to deceive those who encounter it.

In Beware Boiúna, that legend becomes terrifyingly real.

The doctors' routine mission quickly turns into a desperate fight for survival when the ancient creature awakens and begins reclaiming its domain.

Trapped deep within an environment where civilization offers little protection, the group must find a way to survive both the unforgiving rainforest and a predator that knows the territory considerably better than they do.

They came to the Amazon hoping to save lives.

Now they're entering a world where nature decides who gets to leave alive.

Beware Boiúna arrives in theaters October 2, 2026.
