One morning, when Riley (Chantel Little) should be at classes, her mother Angie (Maissa Houri) hears a cellphone ringing from her bedroom, soon to discover Riley left her phone behind. She answers what is Riley's best friend Mackenzie's (Willow Mcgregor) third attempt to reach someone. After Angie asks if Riley is with her, she realizes Mackenzie was about to ask the same thing.
