Possessor Uncut

In an alternate 2008, skilled assassin Tasya Vos uses a unique method to carry out her contracts. She takes control of other people's bodies with a specialized machine, allowing her consciousness to execute her missions from within her victims.

The grim nature of her assignments necessitates a tragic conclusion: each time she completes a mission, Tasya must force her host to commit suicide to return to her own body. This dark requirement leads Tasya into a moral and emotional quagmire.

As Tasya immerses herself in the lives of her victims, she begins to lose touch with her identity. The boundary between her professional obligations and personal relationships starts to blur, particularly influencing her interactions with her husband Michael and son Ira.

Her handler, retired hitman Girder, expresses concern that Tasya's emotional connections are detrimental to her effectiveness as an assassin. He emphasizes the need for her to remain detached to successfully navigate her violent lifestyle.

During a debriefing session intended to restore her mental stability, Tasya reflects on mementos from her past, including a butterfly she once pinned. This moment reveals her buried guilt over the butterfly's death and acts as a metaphor for her own emotional turmoil.

Despite her unraveling mental state, Tasya accepts a high-stakes job targeting wealthy CEO John Parse and his daughter Ava. The plan involves taking over Ava's fiancé, Colin Tate, showcasing the risks associated with her profession.

As the mission unfolds, Tasya successfully orchestrates the events leading to Ava's death while Parse survives. This partial victory leaves Tasya grappling with the consequences of her actions and the emotions tied to her job.

In a bid to regain control over Colin Tate's body, Tasya attempts to force him to commit suicide. However, in a moment of rebellion, Tate stabs himself, damaging the implant and creating chaos in the process.

As Tate regains control of his consciousness, he is plagued by intrusive memories of Tasya's life, leading him to flee to his friend Reeta's apartment. The turmoil escalates as he inadvertently kills Reeta in his disrupted state.

Eddie, an associate of Tasya's, arrives to help her regain control over Tate. However, their efforts are futile as Tasya struggles against Tate's will, leading to a psychic confrontation and increasing the stakes for all involved.

In a devastating climax, Tate confronts Tasya at her home, holding her husband Michael at gunpoint. During the struggle, Michael is fatally wounded, and in a frantic moment, their son Ira attempts to save his mother but is tragically shot by Tate.

After the tragic events, Tasya eventually returns to her own body, only to discover that Girder has taken extreme measures. He controlled her son Ira to eliminate the remnants of her connection to Tate, resulting in a complete severance from her family.

With her family gone, Tasya finds herself devoid of any human attachments. This aligns with Girder's intent for her to achieve emotional detachment, which was paramount for her role as an assassin.

In a concluding debriefing, Tasya revisits her memories from earlier, once again handling the butterfly. However, she now exhibits a chilling absence of remorse for taking lives, signifying her complete transformation.
