As in the original fairy tale, Hansel and Gretel as children are abandoned by their father in a forest, where they come across a house made of candy. Upon entering it, they are captured by a cannibalistic witch, who makes Gretel prepare the oven while forcing Hansel to continuously eat sweets to fatten him up. The children outsmart her before she could eat them, incinerating her in the oven. Over the following many years, Hansel and Gretel, now in their adolescence, have become famed witch hunters, slaying many witches without succumbing to harmful spells and curses of the witchcraft; although the incident in the gingerbread house has left Hansel with a magic-induced form of diabetes and he needs to inject himself with a shot of insulin every few hours.
