The game is centered on the six-year-old-boy Lucius, the son of Lucifer, who murders members of his household, using powers of telekinesis and mind control to orchestrate deadly accidents that lead to the deaths of multiple residents of Dante Manor.

Lucius' childhood is spent in the luxurious manor house on the private estate of his father, Charles Wagner and his wife, Nancy, was as normal as every kid's young years, excluding the extreme wealth of his parents.

Over the next few months, Lucius carefully picks off the manor's inhabitants through both everyday household objects and a small roster of supernatural powers that he gains over time.

Catching his uncle Tom having an affair with one of the housemaids, Lucius plants false evidence that pits the blame on another maid, Jovita.

Staging her death as a suicide, Lucius then kills an alcoholic and repressed Tom by poisoning one of his bottles using a vial hidden in a satanic ritual room located behind the manor's wine cellar.

In the aftermath of both deaths, McGuffin finds himself in hot water over the journalist's disappearance and a worried Charles stumbles upon a book detailing his father's satanic rituals.

As he tries to find evidence to prove this to a mentally-unstable Nancy, Lucius plants a nail-gun and forces him to kill her using his supernatural powers as McGuffin and his deputy arrive on the scene.
