Oz Bezarius (also spelt Vessalius) spends his 15th birthday running away from the maids with his younger sister, Ada and servant, Gilbert. They hide out at Oz's secret spot, where he accidentally falls through the ground leading to a hidden cemetery. There's only one grave there, and a pocket watch is attached to it. As Oz grabs the pocket watch from the tomb, he sees a vision of a homicidal girl before being brought back to reality by Gilbert. While he prepares for his coming of age ceremony, strange figures gather and prepare to carry out their scheme.
