In a small town in Oklahoma, a divorced mother, Callie, and her two children, Phoebe and Trevor, move into the mysterious house they inherited from their grandfather, a stranger to them. Soon, the three begin to uncover hidden secrets in their ancestor's home, which hold an astonishing link to the past of ghost hunters. Phoebe, a bright and somewhat nerdy teenager, finds an old trap and a piece of science equipment that doesn't seem entirely normal. Meanwhile, Trevor is drawn to an old police car, which turns out to be the iconic Ecto-1.
As paranormal phenomena begin to occur in the town, Callie and her children realize that their grandfather was one of the original ghost hunters. With the help of a group of new friends—including a local old-timer with more knowledge than he appears to have—Phoebe and Trevor embark on an adventure that will lead them to confront supernatural entities and uncover the family legacy they carry within them.
With nods and tributes to the classic film, this new installment blends nostalgia and humor, as the protagonists must unite to save their home and the world from a threat that has been dormant for decades. In the end, family bonds become the true power that can face the unknown. Get ready for action and laughter!
