Lucy Castillo, a young med student, has just given up a prized summer internship to bail out her troubled younger brother, Sal... again. He needs cash fast, and after being unable to find a job, Lucy reluctantly accepts the too-good-to-be-true position as a housekeeper offered to her through a friend of a friend. For only three weeks work, she will be paid enough to get Sal out of trouble. Things start to take a disturbing turn, however, as the job reveals itself to be anything but normal. Her never-seen employer seems to have a dark side, and Lucy's own haunted past begins to reappear, tormenting her. As the job spirals out of control and Sal's life hangs in the balance, Lucy's grip on reality disappears.

When Mia, a social media star, becomes the target of an online terror campaign, she has to solve a series of games to prevent people she cares about from getting murdered.
