Simon and Clara, a pair of self-proclaimed paranormal investigators, chase after a ghostly old 1917 police car as it races through Caligo Falls toward a creepy old shack in the forest where a shocking murder took place in 1922, sending the two best friends off on a sometimes terrifying quest to solve a long forgotten series of murders and clear the name of Bobby Finch’s grandfather, a destitute World War I veteran who had taken his own life.

With help from a few of their ghostly friends, Simon and Clara must utilize all their investigative skills to solve the four heinous murders before they head off to college in the fall.
