After working long days, Trey always looks forward to going home to her loyal dog, Nitro. Until one day, when a strange occurrence with an elderly hospice patient seems to change Trey's life, and the odd energy follows her home. At first, only Nitro seems to notice the strange presence. The normally loving and dependable dog begins acting differently, staring into empty spaces, reacting to things no one else can see, and behaving in ways that leave Trey deeply unsettled. As Nitro's personality continues to change, unexplained events start occurring throughout the house. Strange noises, unsettling encounters, and increasingly disturbing activity make Trey wonder whether something dark has attached itself to her family.
