Elias and Noor are now the only children left at AstroCampen, and they have got a slightly unrealistic idea of how to get Mie and Johannes home. For once, Bolette-Henriette has a better plan, which, however, involves Panda-Søren, who is not fully involved in it. Mie, Johannes and Mette dream of returning to Earth, but to their great frustration, Viggo has not fully kept his promise. At the same time, a mysterious fog is spreading in the corridors, and they are surprised that they do not see anything until the 9s.
