In the morning of arendelle there was sisters named Elsa and Anna Elsa had C. magical powers since she was born but her sister Anna is a normal human
She was afraid of her powers but when her mom and dad was about to go on search for the cure there was a terrible storm while they were at sea the ship sunk and nobody survived. A few years later it was time for Elsa to take the throne but she was not so sure if she could handle arendelle and keep her powers hidden in coronation day Anna was so exited because they were free at last then while singing she bumped into a prince and fell into a boat but they found each other very close and giggled Anna introduced herself as a princess and Hans introduced himself too Anna went back to the castle in time for the in time for the coronation and she found Hans in the ballroom and they went upstairs and sang love is an open door they found out they had so much in common and they were so happy they planned they would engaged but Elsa does not like them to get ingaged and the wo sisters argued Elsa accidently made sharp shards of ice and got afraid and ran outside and all the peaple happily greeted Queen Elsa in coronation day but she froze the fountain and everybody got scared she ran away into the mountain and made a castle made of ice and Anna traveled to get there she either met kristoff and Olaf they went there and Elsa went up to the top of the ice castle and she struck Anna in the heart they had to rush back into the castle and let Hans take care of her and it was a trick he locked Anna in the room but luckily Olaf went inside and carried Anna outside and kristoff noticed that he needs to save Anna
They were struggling in the storm but Anna saw that Hans was about to kill Elsa but instead of her life she risked hers to save her sister after that she felt so sad she cried and Anna went back again and Elsa lifted the storm
