But soon after Group B5 arrived at their planetary camp site, a mysterious and unforeseen sentient light sphere warps its 9 members into outer space, stranding them 5012 light years away from their home planet. With the discovery of an old, unmanned spaceship nearby, the students must stay strong, manage their limited resources and remain united in the darkness of space, so that all of them can survive their long and likely perilous trek back home aboard the Astra.
