In the picturesque kingdom of Arendelle, surrounded by the sea, there live two lovely and beautiful little princesses, Elsa and Anna. Elsa is born with the ability to make ice and snow. As she grows older, her ability becomes stronger and stronger, and she almost takes her sister's life. For this reason, the king closed the palace door and cut off the contact between the two sisters. After the sad shipwreck, Elsa (voiced by Idina Menzel) finally reached the age of coronation, and the princes of various countries came to congratulate her. Elsa was trembling with fear, fearing that the secret hidden for many years would be discovered. However, when she heard that Anna (voiced by Kristen Bell) was going to marry Prince Hans of Southern Els (voiced by Santino Fontana) whom she met for the first time, she still lost control of her emotions and exposed her feet. After that, she fled to the mountains and built her own ice and snow kingdom, and Arendelle fell into a terrible cold. Anna came to the mountains alone, and with the help of the mountain man Kristoff (voiced by Jonathan Groff), she finally came to her sister's palace. Can she help the country regain its lost greenery?
