The cartoon starts out showing a storybook of the Queen of Hearts story. A joker card is clipped to the top of the page. The Joker comes to life and wakes up the King, Queen, and Jack of Hearts. He says to enjoy themselves but be back by the stroke of 12. The King of Hearts orders some tarts, and the Queen is proud to make them. An army of living hearts help her add the ingredients...but, will they make it back to the deck of cards before 12?
