There is a mysterious white river, one that holds the answers to the _x000D_
past. But it's just in a lullaby that Anna and Elsa's mother sings to _x000D_
them. Or is the white river actually real? Anna and Elsa leave the _x000D_
comfort of their bed to look for it in the forest. It could hold the _x000D_
answers to why Elsa has magic--that is, if it exists at all . . .
