Anna sets out to find Elsa and end the freeze. She meets an iceman named , his loyal reindeer Sven , and a magical snowman named Olaf (created accidentally by Elsa as a child). Olaf dreams of experiencing summer, unaware that he would melt.
They return to Arendelle, where Hans appears to be Anna’s only chance for true love’s kiss. But Hans reveals his true nature: he never loved Anna and plans to kill Elsa and rule Arendelle. He locks Anna in a room to die and goes after Elsa.
At Elsa’s icy palace, Anna tries to convince her to return. But Elsa, overwhelmed, loses control and strikes Anna in the heart — freezing it. Elsa then conjures a massive snow monster, Marshmallow, to throw them out. As Anna grows weaker, Kristoff races her to the trolls, who reveal that only “an act of true love” can thaw her frozen heart.
