In a near-future world where corporate espionage has taken a sinister turn, technology exists that allows agents to inhabit others' bodies to execute high-profile hits. One such agent, Tasya Vos, works for a secretive organization that uses brain-implant technology to possess civilians, turning them into unwitting puppets to carry out assassinations. Tasya, an elite operative, struggles with the psychological toll her job exerts on her, causing a strain on her personal life and inner identity. Her dedication to her work comes with a fascination for the momentary lives she leads while controlling others, causing her to lose grip on her own sense of self.

Tasked with a new assignment, Tasya is instructed to take control of Colin Tate, a man with a strategic relationship to her high-profile target. The initial takeover goes as planned, with Tasya entering Colin's body and beginning to manipulate his actions to set up the ultimate assassination scheme. However, what begins as a routine mission rapidly descends into chaos when the fusion between Tasya and Colin's consciousness becomes more contested than anticipated. As she delves deeper into her host's life, the lines between her reality and Colin's begin to blur, leading to an intense internal battle for dominance and self-preservation. This confrontation not only threatens the mission's success but also forces Tasya to confront the morality of her actions and the monstrous nature of her work.
