Fearless optimist Anna (voice of Kristen Bell) sets off an epic journey -- teaming up with rugged mountain man Kristoff (voice of Jonathan Groff) and his loyal reindeer Sven -- to find her sister Elsa (voice of Idina Menzel), whose icy powers have trapped the kingdom of Arendelle in eternal winter. Encountering Everest-like conditions, mystical trolls, and a hilarious snowman named Olaf (voice of Josh Gad), Anna and Kristoff battle the elements in a race to save the kingdom.
