Fifteen-year-old Lynn Marie Sugrue is doing her best to make it through a difficult summer. Her mother works long hours as a nurse, and Lynn suspects that her mother's pill-popping boyfriend has enlisted her in his petty criminal enterprises. Lynn finds refuge in online flirtations, eventually meeting up with a troubled young soldier, Logan Loy, and inviting him home. When he's forced to stay over in a storage space accessible through her closet, and the Army subsequently lists him as AWOL, she realizes that he's the one thing in her life that she can control. Meanwhile, her mother's boyfriend is on the receiving end of a series of increasingly violent threats, which places Lynn squarely in the crosshairs.
