The team travels to one of the largest insane asylums known for lobotomies and electroshock therapy. They will search for the spirits of neglected children, abusive nurses and attempt to lure out Dr. Fear. Yes, that's his real name.

In the climactic conclusion, the Haunter team explores the infamous Candy Land and dangerous underground tunnels. And, in a surprising twist, the infrasound machine reveals a new tactic.

Full of bonus, never-before-seen footage, deleted scenes and more, the Haunter cast sits down with director and co-creator Daniel Fabelo to discuss this season's most ridiculous moments and review some of their most haunting evidence.
