The Other User

In the techno-thriller "THE OTHER USER, " Carla Hartman believes she has built a high-tech fortress to protect her three sons from a traumatic past. But when she leaves them alone for a brief supply run, the sanctuary becomes a trap. A predator from her history, Victor Hale, has "grafted" himself into the house's nervous system, bypassing security protocols and using a vocal synthesizer to mimic Carla's voice to manipulate her children.
As the lights die and the thermal cameras wake under a stranger's control, the three brothers must navigate the secret maintenance shafts and crawlspaces of their own home to survive.  Victor isn't just breaking in; he's teaching a lesson in fear. Carla is racing back through a mountain storm, but she may find that the hardest fortress to breach is the one she built herself.
