Meghan Michaels’s phone rings while she’s at the store. She sees a missed call from her daughter, Sienna Long, and gets worried because Sienna is supposed to be at school. She picks up Sienna’s call and asks if Sienna is okay. Instead of hearing Sienna’s voice, Meghan hears movement on the line and realizes that Sienna accidentally called her. Then a man comes onto the phone and says that Meghan has to do what he says or she’ll never see Sienna again. Frantic, Meghan starts yelling into the phone. She hears Sienna calling for her and demands to know what the man wants. The man again tells Meghan to listen to him or something will happen to Sienna.
