Hansel and Gretel are on their way to Storybrooke.

A week after Once Upon a Time took viewers inside the world of Rumplestiltskin, the ABC smash will air its take on another classic fairy tale.

On the episode "True North," look for Emma to offer assistance to a pair of homeless children in search of their birth father. Meanwhile, in the land sort of very far, far away...  the Evil Queen will coerce Hansel and Gretel into swiping a vital artifact from a blind witch.
