Siblings OJ and Emerald Haywood inherit their father's horse ranch in Agua Dulce, California, following his mysterious death, which appears to be caused by random objects falling from the sky. The ranch, once prosperous by supplying horses for film and television productions, is now struggling financially. The Haywoods notice strange occurrences around their property, including the horses becoming spooked and erratic power outages. Their investigation into these events leads them to believe that something otherworldly may be present in the skies above their ranch. An encounter with a reclusive tech salesman heightens their suspicion that they're dealing with a phenomenon beyond human understanding.

Determined to capture evidence of this anomaly, the Haywoods embark on a plan to photograph and expose the truth, seeing it as an opportunity to regain their financial stability and claim fame. They join forces with the tech salesman and documentarian Antlers Holst, who has his own motivations for capturing the spectacle. Together, they set up surveillance and begin to decipher the patterns and behaviors of the unexplained occurrences. As their pursuit intensifies, the Haywoods' ambition to seize control of the narrative of their discovery puts them in increasingly perilous situations, challenging the very fabric of their family bonds and their connection to reality.
