Stephanie and Ellie, two young American women, are on a biking trip through the picturesque yet isolated countryside of Argentina. Their vacation takes a dark turn when they decide to explore an off-the-beaten-path village. After a heated argument, they part ways for a brief period. Stephanie goes to a nearby café, while Ellie stays by the river alone. When Stephanie returns, Ellie is nowhere to be found. As panic sets in, Stephanie realizes that her friend has disappeared without a trace, and with little to no help available from the local authorities, she's forced to investigate on her own.

Stephanie soon meets Michael, a fellow traveler who claims to know about a series of kidnappings that have been happening in the area. Together, they attempt to uncover clues about Ellie's disappearance. The deeper Stephanie digs, the more she senses that someone in the village might be involved. Danger escalates as she gets closer to the truth, forcing her to question whom she can really trust. With time running out, Stephanie must navigate a labyrinth of secrets and dangers to find her friend before it's too late. The tension rises as the sinister reality of their once-idyllic adventure reveals itself.
