Tom, 10, is different from other kids. He avoids change, dislikes the color red, and finds loud noises overwhelming. His passion lies in space exploration, often putting on his astronaut suit. When his mom unexpectedly travels to China, Tom stays with his siblings Nina (15) and Elmar (13) at Grandma and Grandpa‘s in Lunau for six weeks. To cope, his mom gives him a logbook, framing the visit as a trial Mars mission.
“If you can handle Grandma and Grandpa,“ his mother assures him, “you can definitely do Mars.“
Tom dreams of being the first to fly to Mars, and together with his siblings as his crew, he explores the planet ‘Lunau’ and tries to understand Grandma and Grandpa, who live by their own rules.
The film is a touching comedy about an outsider‘s ambitious goals, where his uniqueness becomes his strength, bridging two generations initially as alien as beings from different planets.
