In a single moment, the entire life of a girl Una is turned upside down; her grandpa is abducted by aliens, and her mum collapses and ends up in a hospital. Una, in her basement, discovers that her grandpa is an alien himself whose spaceship hit the planet some time ago, and there's still his pilot, a small grumpy robot. Una and the robot have less than 24 hours to find and rescue her grandpa. This extraordinary adventure will lead to new friendships, the rational robotic logic will be replaced by emotions and Una's selfless love will save her partly alien family.
