After being evicted from their home, two children and their single mother are forced to move to a farm inherited from their late grandfather, located in Summerville, Oklahoma. When the town experiences a series of unexplained earthquakes, the children discover their family's link to the original Ghostbusters, who have become something of a myth as many have long since forgotten the events of the "Manhattan Crossrip of 1984". They discover the secret legacy that their grandfather left behind.
