Every year on October 31, the witch and warlock children of Transylvania jump on their magic brooms and fly into town to take part in the mortal's Harvests celebration. Although she enjoys the festivities, Abigail - the most precocious little witch of them all - wishes to bring back enough mortal treats to share with all of Transylvania to enjoy all year long! One day, after accidentally slipping into her mother's brewing pot, Abigail comes up with a brilliant plan.

Join Abigail as she embarks on a delightful and historical journey to change the mortal Harvest celebration to the miraculous birth of Trick or Treat and how the Switch Witch came to be.
