The house goes up in flames.<br/><br/>The next day, Detectives Tanzy and Byrd witness a horrific video posted online. Someone stood in the back garden filming as Danny and his whole family burned alive.<br/><br/>Across town, four women wake up in a dark, cold room. Every time they fall asleep, one of them is taken. People on the internet are paying good money to watch what happens to them.<br/><br/>Then Tanzy and Byrd get a sickening call. There's an unconscious woman balanced right on the edge of her fourth-floor balcony. Someone drugged her and put her up there.
