Tau (film)

Julia, a young woman who makes money as a thief in seedy nightclubs, is abducted from her home and wakes up in a jail cell with a glowing implant in the back of her neck. Two other subjects are with her. After multiple sessions of psychological torture, she destroys the cell and adjacent lab in an escape attempt. The two other subjects are killed by a robot, Aries, run by an artificial intelligence named Tau. Aries is about to kill Julia when Alex, the man who has been torturing her, arrives and stops it.

Alex reveals that the electrical implant is collecting Julia's neural activity for an AI project. Destroying the lab has set his research back. In the face of a two-week deadline, Alex keeps Julia a prisoner in his house and insists that she complete puzzles and cognitive tests. While Alex is away at work each day, Julia converses with Tau about the world outside the house. It is clear that, although intelligent in its own ways, Tau is ignorant of how people feel or the world at large. While Tau begins to understand the harm in Julia's situation, its programming prevents it from releasing her. In exchange for information about the outside world, Tau slowly reveals more information about the house, as well as Alex's experiments.

Julia sneaks a look at Alex's tablet and discovers that 10 other subjects have died in his experiments. Seeing her fingerprint on the tablet, Alex assumes that Tau has slipped up in its cleaning duties and punishes it by erasing its code and memories, delivering a form of pain to the AI. Julia notices that Tau's monitoring of her shuts down during its punishment and so she hides a steak knife on the floor next to the kitchen table. When Alex returns later that night from a charity benefit, Julia makes as though to seduce him while he is sitting at the kitchen table, then slashes his stomach. The two struggle and Tau threatens Alex with pain if he does not stop hurting Julia. Alex forces Aries to hit Julia repeatedly and then tells both Tau and Julia that whatever was going on is over. While repairing Tau, he disconnects a drone from the network.

The next day, Julia convinces Tau that Alex will kill her if she does not escape. Tau bypasses its prohibition in releasing her by opening an air duct in the atrium. As she escapes, Alex arrives, sees Julia missing, and begins punishing Tau. Julia returns to save Tau, but it is too late—all of its memories of her have been erased.

Alex has Julia strapped down in the basement to extract her implant, a procedure that will kill her. The disconnected drone, still containing Tau's former consciousness and memories, helps Julia break free from her restraints. She knocks Alex out and cuts off his hand with a bone saw to use on the house's biometric sensors. Aries sees her in the atrium and chases her upstairs to Alex's bedroom. As the robot breaks through the door, she uses Alex's severed hand to activate the house's self-destruct mechanism. She narrowly escapes through a cracking wall with the drone that saved her, all that is left of Tau.
