As people across Los Angeles quietly vanish into blinding light, two teenagers journey to a radio tower to send a final broadcast, while a young man and his grandmother confront what it means to stay.

Across Los Angeles, people are quietly disappearing.

There are no explosions, no riots, no panic. A strange, blinding light appears — in garages, in hallways, in backyards — and one by one, people step into it and vanish. Those who remain retreat indoors, waiting. Some pretend nothing is happening. Others simply watch.

Determined not to sit still, a teenage girl drags a reluctant friend to a hilltop electrical tower on the edge of the valley. Armed with a satellite dish, a generator, and a half-assembled transmission rig, they attempt to broadcast something — proof that someone tried to speak before the end. As the city’s lights flicker and the air hums with static, their signal unexpectedly reaches further than they imagined.

Across town, a young man seeks refuge at his grandmother’s house after his parents disappear in a sudden flash of light. As the power fails and the city falls silent, the two cling to routine — cereal at the kitchen table, a broken television, the comfort of familiar music — until the light finds them too.

As the city empties, each of them must choose how to meet the end: to wait, to go, to fight, or simply to listen.
