Eu vi esse filme quando criança no final dos 80s ou no início dos 90s. Nele, uma garota quer ir a um concerto, mas sua mãe não deixa. Eles estão apenas se mudando para uma nova casa. Ela foge e é atropelada por um carro. No hospital, eles descobrem que o sangue dela é azul e ela tem corações 2 (ou talvez apenas um, mas do lado errado?). O vizinho do lado é uma velhinha que acaba sendo uma alienígena enviada para proteger a garota ou algo assim, acho que uma nave espacial a pega no final.
O filme é chamado The Distant Home
Jim and Maria Harrison are an ordinary couple living in an ordinary suburb. The only extraordinary thing about them is that their daughter Sally is about to become ruler of the galaxy.
The Harrisons were expecting their first child. On the way to the hospital the weather was strange, the electrical system of the family sedan failed, and when their child is born, it was unexpectedly twins, a boy and a girl, Bobby and Sally.
What the Harrisons did not know was that the leader of the Galazy Empire was also pregnant at the time. As there was a war between the Empire and the Confederacy, to safeguard the Empires child, it was implanted in Maria's womb and left up to her to raise.
Twelve years pass and the twins have grown up, but the time has come for Sally to return to her real family, and rule as she was meant to. Unfortunately she is knocked over by a car while riding her new bike and is taken to hospital where it is discovered that she is an alien. With the government involved, Sally is unable to return to either family until the Harrisons make plans to rescue her and return her to her real mother and fulfill her destiny out among the stars.
