Beverly Hills sorority queen Elle (Reese Witherspoon) is shocked when her boyfriend Warner (Matthew Davis) takes her out for a meal and then dumps her, saying that because he is about to attend Harvard Law School, he should now start dating a more serious-minded woman.

The epic adventure follows the journey of a robot--Rozzum unit 7134, "Roz" for short -- that is shipwrecked on an uninhabited island and must learn to adapt to the harsh surroundings, gradually building relationships with the animals on the island and becoming the adoptive parent of an orphaned gosling.
