Everyone has a secret. For Raven Fields, this secret is hard to hide. With a large cast on her right leg, it draws suspicion. Why does she have a cast? Answer; she has three legs. Two right, one left. The cast holds both right legs. Raven keeps this secret to herself, but when its revealed, her fellow students call her a freak. So, she moves to Gravity Falls to get away from her troubles, and finds out she's not alone.
After meeting a six fingered man, fourteen year-old twins, and the sixer's twin brother, she is noticed by the one and only Bill Cipher, who is now trying to ruin her life in every way possible.
Its up to Raven, and both sets of twins to stop the evil Dorito from ruining everything.
