The Helluva Bosses Go to Hell

Title: "Nightmare from Underworld" The film opens with the Johnson family - John, the father, Martha, the wife, Scott, the teenage son, little Nathan, and the youngest Anna - moving into their new house in the quiet town of Everbrook. Scott, a horror enthusiast, quickly takes interest in the town's haunted past. The house is rumored to be built over a supposed hellgate, but the family dismisses it as local legend. One night after the move, Scott finds an ancient book in the basement - 'Arcanum Inferni'. Seeing it as a collector's item, he reads it out loud, unknowingly reciting a summoning spell. That act inadvertently calls forth the four demons; Blitzo, Moxxie, Millie, and Loona, from the underworld. These demons, bored of the underworld monotony, seize the opportunity for some twisted enjoyment - murder. Their menacing presence gradually becomes evident, and the family senses that something is horribly wrong. Pets go missing before neighbors are found dead, and the town is thrown into a frenzy of fear and suspicion. John, although initially skeptical, starts believing the supernatural elements when he observes demonic symbols inside their house. Their once peaceful home is now a haunted mansion with flying objects, chilling screams, and apparitions only visible to the innocent eyes of Nathan and Anna. Martha reaches out to the town's priest, Father O'Conner, who, after assessing the situation, identifies their terror as the Imps and the hellhound from Hell's legends. He educates them about their weaknesses - faith, holy objects, and the power of a pure soul. He gifts Martha a blessed amulet rumored to protect the owner from the demonic powers. Meanwhile, Scott, realizing the disaster he caused, ventures out to learn more about the closing spell, which is rumored to be lost in the town's old library. The setting turns grim when demons infiltrate the town's festival to cause havoc, giving Scott a narrow window for his quest. The family then rallies together, using their trust in each other to withstand fear. Nathan and Anna, with their pure souls, cause the demons pain, disrupting their powers whenever they try to harm them. They arm themselves with holy water and crosses, standing against evil. Scott miraculously finds and deciphers the closing spell while narrowly escaping Loona's attacks. He races home, understanding how little time they have left. Despite his injuries, he starts reciting the closing spell. The climax ensues as each family member battles the demons, distracting them long enough for Scott to finish the spell. As evil is conquered, the Johnson family watches as Blitzo, Moxxie, Millie, and Loona are eventually swallowed back into the underworld's fiery pit. 'Nightmare from Underworld' ends on a terrifying yet hopeful note, with the family deciding to leave Everbrook. The audience is left to wonder about the fate of the town, the hellgate, and the demons trapped in the underworld - setting a potential opening for a sequel. Throughout the film, the elements of suspense, horror, and family bonds intertwined with humor and wit bring out the essence of a supernatural thriller.
