The protagonist of this children's film, nine-year-old Una, finds it hard to make friends. In fact, her goofy Grandpa is her only friend. One evening, Una witnesses Grandpa's abduction by aliens. Trying to solve his disappearance, Una discovers a secret compartment in the basement, full of alien artifacts. However, her attention is captured by a grumpy little alien robot. This extraordinary find leads to a new friendship. The rational robotic logic gets replaced by emotions, and Una's selfless love ultimately saves her partly alien family.
