Once Upon A Time In the Underworld: Season 1

A young woman, Bianca, is on the run from all kinds of mythological monsters. While hiding out in the woods, she's caught off guard by the Chimera. It kills her quickly and painfully. She wakes up in an unfamiliar place, a pawn shop filled with the most unusual objects. The owner of the pawn shop tells her she's dead and in the Underworld. She doesn't believe it at first, but slowly comes to that realization. When the ruler of the Underworld comes to her with a job, she reluctantly accepts. She slowly falls into a new routine. This takes place during season 4 of Once Upon A Time.
