And there was light

A scientist named Johann Volcek develops a radical device meant to incapacitate half the world as a humane alternative to apocalyptic weapons, and the narrative follows the mounting preparations and a high-profile demonstration staged by an authoritarian government. Personal strain surfaces through Volcek's grief-tinged marriage and his wife Stefanie's fragility, while political flattery, rival ambitions, and public spectacle crowd the laboratory. The plot concentrates on the moral and practical consequences of technological fixes presented as national salvation, showing how scientific pride, state power, and private loss collide in the lead-up to a decisive test.
