Frozen 2- Beware the Frozen Heart (the Sequel)

Anna has been kidnapped. Somewhere in the South Mountains she lies captive to yet another power-driven foe. Together Elsa and Kristoff swear to save her, though they are not very fond of each other. Along the way they meet a stranger, with powers similar to Elsa's. They also run into old foes (and new ones), and must prepare for a war between kingdom's that no one is prepared for.
