IGN - A case about a missing girl, Holly, is re-opened when some of her hair is found at a crime scene in the woods. All clues and the subtle episode title point to Rapunzel, and she sort of is. Technically, she's a Blutbad who hasn't had a haircut in nine years. She's been living in the forest, and she killed someone (by strangling him with her hair!) only to protect innocent hikers. Nick spots her while taking evidence from the crime scene and turns to Monroe for assistance.
