Hansel & Gretel: Witch Hunters

The movie begins with siblings, Hansel and Gretel, who are left by their father in the forest and the young children enter into the gingerbread house, where they are trapped by a witch. The witch forces Hansel to eat candy non stop in order to make him fat and asks Gretel to make the oven, but two kids, with their smartness, rescue themselves from the witch by burning her in the fire of the oven.

Fifteen years later, the siblings are the very famous witch hunters, they are known for slaying hundreds of witches. In all these years, they have become witch hunters and realize that they are immune to all the attacks of the witches and no curse or spell of the witch can cause them harm. But a single incident in their childhood, the gingerbread house incident, has made Hansel diabetic and now, he is striving to live, as he is short of insulin every few hours.
After getting a taste for blood as children, Hansel and Gretel have become the ultimate vigilantes, hell-bent on retribution. Now, unbeknownst to them, Hansel and Gretel have become the hunted, and must face an evil far greater than witches... their past.
