What would you do if everyone disappeared tomorrow? Janek wakes up - and he is alone. All people have vanished! In their place, plants and wild animals are reclaiming the city. Confused, Janek wanders through the overgrown streets with a stray dog. He leaves a message on the school chalkboard: "If anyone is still out there besides me: Contact Janek!" The response, a smudged chalk mark, sends Janek into a panic. Who is hiding from him? And why? Suddenly, every shadow, every sound, every movement outside becomes a threat.
