Summary: A woman is driving by the countryside late at night and a figure (woman) falls before the vehicle. At close inspection it seems that this woman has been shot and seems to be dead. The driver goes and reports the incident but when the police visit the scene of the crime, the woman has disappeared without a trace. Did the witness imagine this, or is she the next target?
