It’s been a year since Paige and Nathan Petrovic lost their teenage son, Zach. Nathan and their daughter, Addie, have rebuilt their lives. But Paige can’t recover. She is still in pain, withdrawn and unable to work. To make up for Paige’s lost income, family members decide to rent the vacant bedroom. Surprisingly, Paige seems to feel better when Brandon Wilson, their charming new tenant, enters their lives. Brandon, a local university student, looks like Zach and pulls Paige out of the shell she was hiding in. At first, Nathan and Addie are happy to get Paige back, but as Brandon insinuates more into their family, they begin to see his dark and dangerous side.
