Supernatural x Once Upon a Time Crossover - When Sam and Dean Winchester rock into an unknown town by the name of Storybrooke due to word of a strange temperature drop, they find the people that reside there are about as strange as the monsters they hunt.

While out one night, Sam and Dean find a woman in distress. What follows is very awkward as they are met by a man with a hook pleading with the woman to come home. One-shot. (DISCLAIMER: I DO NOT OWN SUPERNATURAL OR ONCE UPON A TIME OR ANY OF ITS CHARACTERS)

Another crossover: Team Free Will meets Captain Hook, who lends a hand - in more ways than one.

Sam and Dean travel to Storybrooke to investigate what seems like a usual case; but Storybrooke is nothing like what they've encountered, with secrets unlike any other, magic they've never faced, and villains they've never encountered. To save the town, they have to team up with the skeptical town sheriff, Emma Swan, who is harboring her own big secret.

Dean gets a call from an old hunter buddy of his to help with a case, asking him to get information from a witness. Under the rouse of her blind date he meets Emma.

Or is it too late?

Too proud to ask for directions, Dean and Sam Winchester get lost and end up in Storybrooke, Maine. When an out- of- the- ordinary death occurs in the area, the brothers decide to investigate.

What happens when Dean and Sam Winchester find out about the supernatural happenings in Storybrooke?
