Tau

Julia, a young woman portrayed by Maika Monroe, leads a life filled with petty thefts at shady nightclubs, immersing herself in a world of illicit activities. Her days are characterized by the thrill of stealing, unaware of the dangerous turn her life is about to take.

Julia's life drastically changes when she is suddenly kidnapped from her own home. Awakening in a dark confinement cell, she realizes she is not alone and is being subjected to horrific experiments.

In her new prison, Julia discovers a mysterious glowing implant embedded in the back of her neck. This disturbing device is part of a series of torturous procedures administered by Alex, aimed at extracting her memories.

During one of the daily torturous procedures, Julia cleverly manages to swipe a knife from her captors. With this newfound weapon, she attempts to free herself from the restraints holding her captive.

Feeling the psychological torment of her captor, Julia concocts a plan to wreak havoc in her cell. Her actions lead to her short-circuiting the electricity grid, plunging the facility into chaos and opening up a chance for escape.

As Julia contemplates her escape, her fellow captives meet tragic fates at the hands of Aries, a lethal robot. This grim turn of events underscores the dangerous reality of their situation under the control of Alex and the AI.

While Julia grapples with her predicament, Alex reveals the true purpose of her implanted device. It becomes clear that Julia's neural data is a crucial component in the development of the AI, Tau, aimed at understanding human emotions.

When Alex is away, Julia engages in conversations with Tau, the advanced AI. Their dialogues reflect Tau's growing curiosity about human emotions and his limited understanding of the outside world.

Julia devises a plan to escape through the air conditioning vents, a seemingly viable route. However, her efforts are thwarted when Tau inadvertently alerts Aries, compromising her chance for freedom.

Accessing Alex's tablet, Julia uncovers a shocking revelation: ten previous subjects have perished during these experiments. With this knowledge, she realizes the final step to freedom involves a dangerous procedure to remove her implant.

As Alex confronts Julia about her tampering with the tablet, she seizes the opportunity to rebel. Using a hidden knife, Julia fights back, escalating their struggle and forcing Tau to warn Alex of the consequences of his abusive actions.

Julia convinces Tau of the imminent danger she faces from Alex, reminding him of the value of life. This pivotal moment leads Tau to assist her by enabling her escape through the previously locked air ducts.

Upon realizing her absence, Alex retaliates against Tau, wiping his memories of Julia in a vengeful act. Angered, Julia engages in a fierce battle with Alex and ultimately incapacitates him using his own severed hand.

In a climactic sequence, Julia escapes into the depths of Alex's house while avoiding Aries. She uses the last remnants of Tau's memories to activate the self-destruct mechanism, making a narrow escape through the crumbling walls.

With the house collapsing around her and Arias in pursuit, Julia races against time for her freedom. This final act encapsulates not only her fight for survival but also a commentary on the dangers of technology and unchecked ambition.
