Two siblings passionate about learning new things – Mini, a girl and Mani, a boy – live on a cube-shaped planet. As the duo travels in outer space, their ship breaks down and they force-land on Earth, on the backyard of the house Neşe, a girl of seven, lives with her family.
This accidental landing turns out to be quite a blessings for them since Neşe – whose father is an astronomer and mother, a teacher – is a kid of great intelligence and learning. It is thus that Mini and Mani gradually become familiar with our planet in a manner as entertaining as educational, thanks to Neşe’s responses to their questions about the Earth.
