A rural Colombian village is attacked by a horrible sea serpent, aroused by industrial pollution of a nearby lake. Based on a real event that took place in June of 1971.

Why it matters

A gritty eco-horror creature feature that channels 1980s regional genre filmmaking through a distinctly Colombian lens.

  • One of the rare Latin American monster movies of its era, blending folklore with environmental dread.
  • Practical effects on a shoestring budget deliver a tangible, if rough, sea serpent menace.
  • Taps into real-world anxieties about industrial pollution decades before eco-horror became mainstream.
  • For fans of ’70s-’80s creature features and regional cinema curiosities craving something off the beaten path.
