While Maruja the witch is updating her book of recipes for cooking tender young children, Hansel and Gretel happen to drop by her house and end up locked in a cage. Luckily for them, Tom and Tere, a couple of builders specialising in repairing chocolate houses are passing by. While they are mending a hole in the roof, Tom falls through into the house and ends up sending Maruja the witch to the back of the oven and helping the children escape. Furthermore, as soon as the witch disappears, the spell that had turned the children's father into a toad is broken. The happy ending is completed by the reunion of father and children and a visit to the dentist after eating so many sweets.
