Chris Norton, a skeptical filmmaker, sets out to debunk the phenomenon of alien abductions by creating a documentary. He travels to a UFO convention in New Mexico and interviews various individuals who claim to have been abducted by extraterrestrials. Among them is Emily Reed, a woman who asserts that she has been abducted multiple times since childhood and believes she is due for another encounter on her upcoming twenty-eighth birthday. Intrigued by her conviction and detail, Chris decides to follow Emily closely, aiming to capture evidence and expose the supposed hoax.

As he delves deeper into Emily's world, Chris discovers unsettling details and experiences inexplicable events that challenge his skepticism. Alongside Emily's confidante, Peter, Chris gathers footage that suggests there might be more to the abduction stories than mere fantasy. Strange occurrences intensify as Emily's predicted abduction date approaches, forcing Chris to confront his own beliefs and the possibility that what he's been investigating might not only be real but also profoundly more disturbing than he ever imagined.
