Frozen is a 2013 American 3D computer-animated musical fantasy film produced by Walt Disney Animation Studios and released by Walt Disney Pictures. The 53rd Disney animated feature film, it is inspired by Hans Christian Andersen’s fairy tale “The Snow Queen”. It tells the story of a fearless princess who sets off on a journey alongside a rugged iceman, his loyal reindeer, and a naive snowman to find her estranged sister, whose icy powers have inadvertently trapped their kingdom in eternal winter.
Princess Elsa of Arendelle possesses magic powers that allow her to control and create ice and snow, often using it to play with her younger sister, Anna. After Elsa accidentally injures Anna with her magic, their parents, the King and Queen, take both siblings to a colony of trolls led by Grand Pabbie. He heals Anna, but alters her memories to remove traces of Elsa’s magic, warning Elsa that she must learn to control her powers. He also states that fear will be Elsa’s greatest enemy. The King and Queen isolate both sisters within the castle. Elsa shuts Anna out, causing a rift between them. Unable to control it, Elsa can only suppress her power, causing her to become more insecure. When the sisters are teenagers, their parents die at sea during a storm.
When Elsa turns 21, she is to be crowned queen of Arendelle. She is terrified that the kingdom’s citizens might find out about her powers and fear her. The castle gates open to the public and visiting dignitaries for the first time in years. Among them is the scheming Duke of Weselton and the dashing Prince Hans of the Southern Isles, the latter of whom Anna falls in love with at first sight. Elsa’s coronation happens without a hitch, but she still remains distant from Anna. When Hans proposes to Anna, Elsa objects, accidentally unleashing her powers before the court; the Duke brands her a monster. Elsa flees to the North Mountain, where she finally acknowledges her powers, building a palace of ice in which to live a hermit life. In the process however, her suppressed magic engulfs Arendelle in an eternal winter.
Anna ventures out to find Elsa and end the winter, leaving Hans in command. She gets lost, collecting supplies at Wandering Oaken’s shop. She meets an ice harvester named Kristoff and his reindeer, Sven, convincing them to take her to the mountains. An attack by wolves leads to Kristoff’s sleigh being destroyed. On foot, they meet Olaf, a cheerful snowman brought to life unknowingly by Elsa, who offers to lead them to her. When Anna’s horse returns to Arendelle, Hans sets out to find Anna and Elsa, accompanied by the Duke’s minions, who have secret orders to kill Elsa.
Reaching the ice palace, Anna meets Elsa, but when she reveals what has become of Arendelle, Elsa becomes upset, saying that she cannot undo it, and accidentally freezes Anna’s heart, poisoning her. She then makes a giant snow monster named Marshmallow, who chases Anna, Kristoff, and Olaf away. Realizing the effects of Elsa’s spell on Anna, Kristoff takes her to the trolls, his adoptive family. Grand Pabbie reveals that Anna will freeze solid unless “an act of true love” reverses the spell. Kristoff races Anna back home so Hans can give her true love’s kiss. Hans and his men reach Elsa’s palace, defeating Marshmallow and capturing Elsa. Anna is delivered to Hans but, rather than kissing her, Hans instead reveals that he has actually been plotting to seize the throne of Arendelle by eliminating both sisters. Hans locks Anna in a room to die, and then manipulates the dignitaries into believing that Elsa killed her. He orders the queen’s execution, only to discover she has escaped her detention cell.
Olaf frees Anna, and they venture into the blizzard outside to meet Kristoff, whom Olaf reveals is in love with her. Hans confronts Elsa outside, claiming that she killed Anna, causing Elsa to break down and abruptly stop the storm. Anna spots Hans about to kill Elsa; she leaps in the way and freezes solid, stopping Hans. Devastated, Elsa hugs and mourns over her sister, who thaws out, her heroism constituting “an act of true love”. Realizing that love is the key to controlling her magic, Elsa ends the winter and gives Olaf his own snow flurry to survive the warmer climate. Hans is arrested and exiled from the kingdom for his attempted assassination, while the Duke’s trade links with Arendelle are cut off. Anna gives Kristoff a new sleigh and the two kiss. Both sisters are reunited and Elsa promises never to lock the castle gates again.
