An anonymous suicide threat shared on social media causes turmoil at a school. For the students, their parents and the teachers, a race against time begins: who sent the threat? While everyone is on the trail of this question, it turns out that another secret could be involved.

Lena is a cheerful student who firmly believes in happiness and the good in people. As part of a social project, she is sent by the office as a writing coach to Hugo Drowak, who has long since lost his luck and lives alone in a run-down tower block.

When scientist Elena presents a book about the climate crisis on a TV show, she is hit by a storm of criticism. In a documentary, she tries to defend herself against misogyny on the internet. But the virtual threat threatens to become real. An unknown person is stalking Elena, and other events are directed against her family. Or is she just imagining it?
