Glen becomes the only witness to the gruesome murder of a woman living in his house, but telling someone about it is nearly impossible since he's a ghost. He finds himself reluctantly involved and desperately hoping he can silence the victim's ghost, who just won't stop haunting him. The dead woman's spirit becomes more volatile each day, and her hints about her killer's identity are an ambiguous game of charades. Glen struggles to find ways to pass along her messages to keep the investigation moving forward. Unfortunately, it seems hardly a soul can hear his clues, except for one. After forty years as a ghost, Glen is mysteriously yanked away from the peaceful house he's always occupied. He suddenly finds himself surrounded by the living, and facing a very different world from the one he'd left long ago. He hopes that unraveling the truth behind the murdered woman will somehow lead him back to his proper place. As he races to put together pieces of the crime and find ways to communicate to the living, he begins to fear there might be an even darker place that lies beyond being dead.
