Roky is a cute little robot who got lost in the Universe. Fortunately, he managed to land in the house of two siblings, Matilda and Horațiu, two mischievous kids living with their grandmother.
Roky is worried that his mother doesn't know where he is, but by learning about the world on Earth, he befriends the two kids and has a lot of fun. A big fan of cocoa with milk, Roky will want to take the recipe back to his planet, and the beautiful memories will make him promise to return to Earth.
