Grüsse vom Mars

Tom is a 10-year-old who dislikes changes, the color red, and loud places. As an aspiring astronaut, he always puts on his helmet and uniform when things get tough. With his mom heading to China, he has to spend the summer with his hippie grandparents and energetic siblings, which feels like a nightmare to him. His one plan to cope: if he can get through this summer, he'll be ready for a trip to Mars.
