Jeremy Renner and Gemma Arterton star in this action comedy inspired by the Brothers Grimm fairy tale. The film is set 15 years after the young Hansel and Gretel (Renner and Arterton) were abandoned by their parents in the forest and taken prisoner in a gingerbread house by a child-eating witch. The siblings managed to escape, and in the intervening years have taken advantage of their subsequent immunity to bad spells and curses to set themselves up as expert bounty hunters, becoming world-famous for their skill in tracking down and killing evildoers around the globe.

The film follows the brother and sister on their latest assignment - a campaign against evil sorceress Muriel (Famke Janssen) - which they begin to realise may be their golden opportunity for revenge of a more personal nature.
