A group of young filmmakers sets out on a journey to the rural town of Epecuén, Argentina, which was submerged underwater for 30 years following a dam collapse. Now exposed, the town lies in ruins, covered in salt and memories of the past. The filmmakers aim to capture footage for a documentary exploring the eerie landscape and the ghost town's history. Along the way, they engage with the local lore and hear unsettling tales from the few remaining residents.

Midway through their exploration, things take a dark turn when the group encounters the unsettling truth about the seemingly abandoned town. As they delve deeper into the decaying remnants, they become harassed and hunted by a hidden threat lurking in the shadows. They must confront both the supernatural and human horrors left behind in the wake of the disaster as they fight for their survival.
