In the land of Arendelle lived two princesses: Elsa (voice of Idina Menzel) and Anna (voice of Kristen Bell). Elsa was born with the gift of ice. She can create ice, snow and cold temperatures even in the heat of summer. Elsa and Anna often play in the grand ballroom of the castle where they live with their parents the King and Queen, turning the giant room into a winter wonderland any time of year. Once while playing, Elsa accidently hit Anna in the head with a blast of her powers, knocking Anna unconscious.
