Kids with smartphones and a half-broken drone orbiting Earth, solving impossible problems because the alternative is dying in the black. The show strips away rescue fantasy, no adults are coming, and builds its entire tension from the fact that every decision compounds, that a choice made in episode two echoes through episode six as consequence, not plot convenience. It's sci-fi that trusts you to care about the math of survival, not just the spectacle of it.

In 2045, AI has advanced, the internet reaches out into space, and space travel is open to everyone. Children born on the moon meet children from Earth who are visiting space, aboard Anshin, a space station built by Japan. When a massive accident hits the station, the group is left stranded. Relying on narrowband connections, social networking, low-intelligence AI and drones they steer from their smartphones, they fight their way through one crisis after another in this six-episode sci-fi adventure.
