Inspired by the many myths and legends surrounding Disney's classic Haunted Mansion attraction, GRIM follows Jason Holloway, a historian obsessed and perhaps even haunted by the stories of the old Gracey estate in New Orleans. His search for answers takes us on a journey through history as we see the tale of the Gracey family unfold throughout several ill-fated generations. It is a tale of lovers, pirates, tycoons, mystics, and murderers, all part of a puzzle that leads to a truth laying in wait, hiding just below the surface. But be warned, friends. The truth can be quite GRIM.
