Along the way, they face a lot of exciting surprises and breath-taking adventures: a meeting with the mystical trolls, acquaintance with a charming snowman named Olaf, mountain peaks more abrupt than Everest and magic in each snowflake. Anna and Kristoff will unite and confront powerful elements to save the kingdom and those who are dear to them.
