Fifty years ago, a girl walked into the woods with only matches to guide her and then disappeared. Days later, her dead body came out without her heart and upon her skin was written a dare:

"Come into the woods and find my still beating heart."

It's a silly urban legend, or at least, it's supposed to be. Over the years, many have followed the dare and many of the same have disappeared or come out just as dead, prompting the city to declare the woods off-limits.

Not that off-limits ever stops would-be urban legend debunkers...

When high schooler Felix Graves agrees to help his classmates debunk the urban legend of the Devil in the Woods once and for all, he doesn't believe there's anything to it.

Until something finds him in the dark.
