As the film begins, we are greeted by a mesmerizing sight: blue lights, resembling flares, cascade down upon Los Angeles at night, illuminating the terrain below. We focus on a young couple, Jarrod and Elaine, who are abruptly stirred awake by the eerie glow outside their window. Initially mistaking it for morning, Elaine rushes to the bathroom, feeling nauseous. Upon her return, the room trembles violently, prompting Jarrod to investigate the commotion. He is halted by the anguished cries of Denise, who reveals that the lights have taken Ray. As Jarrod gazes into the light, a horrifying transformation begins, with blue/black veins creeping across his skin, leaving his eyes clouded and opaque. Soon after, Terry and Candice, his girlfriend, awake and join the fray, as Jarrod's instinct draws him towards the ominous light.
Flashback to 15 hours earlier: Jarrod and Elaine arrive in Los Angeles from New York, ready to celebrate Terry's birthday. Terry, once a childhood companion, has flourished in his career with a special effects company. He greets them at the airport in style, and the duo is soon introduced to Candice and Denise. They indulge in a lavish pool party, oblivious to the approaching danger above, despite Homeland Security helicopters surveilling the area. A celebratory atmosphere soon shifts when revelations come to light: Terry's unscrupulous affair with his assistant Denise casts a dark shadow over the festivities.

Back in the apartment, the others find the TV stations eerily inactive, failing to explain the bizarre occurrences.
