Eric builds up a head of steam as he becomes more and more annoyed by the antics of his little sister, Alice-she's always messing with his stuff, and when he gets mad at her, his parents blame him! Things come to a head when in a particular fit of pique, a furious Eric floats up to the ceiling. Unable and unwilling to heed his parents' orders and pleas to come back down, Eric makes his way out a window and into a nearby tree. At first he feels empowered by being free of his family, but when his lack of gravity starts to pull him toward the lonely ether, he asks for, and gets, help. Eric gains some appreciation for Alice along the way, and a view of how she always wants to be just like him (especially when she shows a bit of gravity-defying temper herself!).
