In an alternate 2008, a woman named Holly Bergman sticks a probe into the top of her head and turns the dial button on a machine. Afterwards, she attends a party as a hostess for the Blue Night Sky Lounge, where she unexpectedly attacks and brutally murders a wealthy attorney. She takes out a gun and puts it in her mouth, but then aims it at the police, who shoot her dead. In a futuristic facility, a woman named Tasya Vos is removed from a conical machine. She is a "possessor": a contract killer whose consciousness is implanted into the body of another person in order to carry out an assassination. Tasya was controlling Holly’s body and committed the murder, but couldn't overcome Holly's resistance to committing suicide.

During a post-assassination debriefing by her boss Girder, Tasya identifies objects of her past to prove that her sense of self is intact. One of the objects is a mounted butterfly, which she expresses regret for killing as a child. She wants time to reconnect with her estranged husband, Michael and son, Ira. When she visits them, she must rehearse how to engage in ordinary conversation, showing that she is unsteady in civilian life. Tasya's next job is one of the biggest ones the company has ever received. They've been hired by Reid, the stepson of John Parse. John is the CEO of a massive corporation, Zoothroo, which operates in data-mining. Reid wants them to assassinate both John and his daughter, Ava, so that he can inherit the company. Girder is excited because, once the job is done, the company will also be able to control Zoothroo via blackmailing Reid.
