When a nervous breakdown abruptly ends her Fall semester and damages her laptop beyond repair, Ally Dennis travels to the town of Vaughnsville, Minnesota to spend time with her estranged father, Paul, who runs a small honey bee farm in the countryside. For the first couple of days, things are about as well they can be, complete with helping on the farm and playing with her father's new dog, but she continues to stress over her need of a new laptop and eventually takes Paul's advice to search an online marketplace for a used one. As luck would have it, a student in town is selling his old laptop for a great price and Ally agrees to meet with him to pick it up. She's startled when a news broadcast the next day reports said-student as having been found dead, a masquerade mask covering his face. The police announce it as the work of the elusive Masquerade Killer, dismissing it as another one of his randomly targeted homicides... however, the combination of both a persisting worry and several frightening incidents makes Ally begin to think otherwise...
