When Marshall Lee gets framed by the Ice Queen, Fionna is determined to prove he's innocent. And with a visitor from the gender-swap dimension, Fionna could do that. With the help of all the adventure time crew they could stop the Ice Queen and her evil plan of destroying the Candy Kingdom. A certain romance between the Vampire King and Candy Prince himself might just end up helping to win the fight. (( I do not own the Adventure Time Characters and/or original story plot line))
