Laura is a seven-year-old country girl, who just moved along with her family to a big city. On her first night in her new neighborhood, she sees a shooting star falling to Earth. Laura finds the star in a park and discovers that it is a living being. The star had severed one of its points during its crash landing. Laura takes the star back home, in order to reattach its point with a band-aid.
Laura and her younger brother Tommy discover the little star has super powers and can do amazing things; like making people fly and bringing inanimate objects to life. But over time both notice that the longer the star stays on Earth, the weaker it becomes. (Its color is gradually fading while its powers fail.) The siblings and their next-door neighbor Max eventually find a way to send the little star back into outer space.
