Alice (Saxon Sharbino) and her friends are teens like any other – social and tethered to their devices. When they download the latest Siri-like App offering quick solutions to life’s quotidian, the friends soon discover the App offers much more than directions and places to eat. So much more. The App probes the teens’ deepest fears, manifesting these fears in the real world in a diabolical quest to terrorize its unwitting users to death.
