Ever since she was little, Juliette's time-traveling grandfather has brought her toys from humanity's history before the nuclear fallout that decimated the species.
The "toys" that her grandfather brings her are actually humans from the past. Juliette, a nymphomaniac sadist, enjoys torturing and murdering them as her proud grandfather looks on. Morally deranged and nihilistic about humanity's future after the nuclear fallout, her grandfather wants to feed her wickedness in the hopes that she destroys all that's left of humanity one day.
One day, her grandfather brings back a Victorian man. Based on his medical bag, they speculate that he might be a doctor. But as Juliette reaches for her knife to deliver the blow, she realizes too late that the Victorian stranger had gotten there first. He brutally stabs her to death. Meanwhile, in Victorian London, Jack the Ripper was never seen again.
