They couldn't be more different, the members of the trio that allies in the fight against an Ancient Ice Ghost (AIG): Tom, an easily scared boy, Hetty, a professional ghosthunter and the loveable, but pretty slimy Hugo - a ghost. Will the team manage to save their town from the next ice age?
Unfortunately the movie Ghosthunters: On Icy Trails is not yet available on HBO Max.
