Tau

Julia is a loner who makes money as a thief in seedy nightclubs. One night, she is abducted from her home and wakes up restrained and gagged in a dark prison inside of a home with two other people, each with an implant in the back of their necks. As "subject 3," she endures a series of torturous psychological sessions by a shadowy figure in a lab. One night, she steals a pair of scissors from the lab and destroys the lab in an escape attempt, but she is stopped and the other two subjects are killed by a robot in the house, Aries, run by an artificial intelligence, Tau.
