It is the first Christmas season since the gates reopened and Anna (Frozen) and Elsa (Frozen) host a celebration for all of Arendelle. When the townspeople unexpectedly leave early to enjoy their individual holiday customs, the sisters realize they have no family traditions of their own. Elsa laments the fact that because she had isolated herself most of her life, she and Anna were unable to spend time with each other. Olaf (Frozen) decides to look for traditions with Sven (Frozen)'s help.
The Frozen franchise is about the adventures of Queen Elsa of Arendelle, her sister Princess Anna, Anna's boyfriend Kristoff who was raised by trolls, and Olaf who is a magic snowman created by Elsa's ice powers. Those very powers tend to set off most of the stories in various ways.
