The Ice Queen Freya (Emily Blunt) is gentle and kind by nature, but she becomes cruel and crazy because of the despair of losing her daughter. She and her evil sister Ravenna (Charlize Theron) have established a cold and bone-chilling ice kingdom, using cold and ruthless rules to maintain their rule, and even set a rule that no love is allowed. Violators will be punished terribly. The hunter Eric (Chris Hemsworth) met the warrior Sarah (Jessica Chastain), and the two fell in love uncontrollably, violating a taboo. In order to be able to live with the people they love, Eric and Sarah decided to join forces to overthrow the tyranny of the two queens. This small rebellion gradually grew into a confrontation between the two camps. When she learned the truth about her daughter's death, what choice would the Ice Queen Freddy make?
