Its either a Disney channel movie or a nickelodeon movie I believe... its probably over 15 years old. I think it was two brothers and a little sister and their parents... they lived in a country town and aliens took over the town and took their parents... the three kids went to go save them and at the end of the movie when they're all in the car driving back I think they find out that there parents are aliens! I can't find it anywhere and I don't know the name... can someone help me ?
