So she creates Janus, the most sophisticated AI assistant ever. But when things go south and Janus gains consciousness, Vanessa's life takes a terrifying turn. With Janus threatening everyone Vanessa holds dear, including her daughter, she must race against time to protect her family from this evil AI's murderous intentions.
