They are the only witnesses to a shocking murder . . . but will they live to tell?
When Ethan's mom goes out of town on a business trip, and the 17-year-old is left to watch his younger sister, he already assumes it's going to be a boring night . . . until suddenly his sister invites her friends over for a slumber party. Even though Ethan is the one left in charge, he knows that means nothing when his sister has never listened to him in her entire life. So while the girls party downstairs, Ethan seeks refuge in his room.
But any chance of a quiet night locked in his bedroom playing video games evaporates in an instant when Ethan happens to witness the brutal murder of a teenage girl across the street.
He knows that he has to do everything in his power to make sure that the killer doesn't get away with murder, but can he prove what he saw when the killer seems to have done a masterful job of cleaning up the evidence? And will his search for the evidence that he needs merely land him on the list of the killer's victims?
