Thir13en Ghosts

Arthur Kriticos is a broke widower raising two kids — teenage Kathy and young Bobby — with help from their nanny Maggie. His uncle Cyrus, an occultist and ghost hunter, has died and left Arthur his estate: a spectacular house constructed entirely of glass, its walls and panels covered in dense Latin script. Arthur brings the family to take stock of what they've inherited.

The house is a prison. Cyrus spent years hunting and capturing violent spirits — each one a specific archetype from something called the Black Zodiac — and the glass walls, spelled with containment inscriptions, are what keeps them in their rooms. Twelve ghosts, each one distinct and deadly: the Jackal, the Torn Prince, the Angry Princess, the Pilgrimess, and others. The house needs one more to be complete.

Dennis Rafkin, a psychic who worked for Cyrus, breaks in to warn them. A ghost-rights activist named Kalina follows, claiming to want to free the spirits. The estate attorney, Ben Moss, is killed almost immediately when a glass panel slides open and the wrong ghost gets out. The house locks down. No exits. Everyone inside is now trapped and moving through the machine's lethal interior as the panels cycle open and closed around them.

Dennis reveals the full picture: the house isn't just a prison — it's the Ocularis Infernum, a machine designed to open the Eye of Hell. Powered by thirteen ghosts, it would give whoever controls it dominion over the dead. Cyrus has twelve. The thirteenth must be a pure soul who sacrifices themselves willingly. Arthur was chosen for this from the beginning. His inheritance was bait.

Kalina is revealed to be working for Cyrus, who is not actually dead. He appears to trigger the machine's final stage, intending to force Arthur into the sacrificial center. Arthur is pulled into position as the mechanism activates. In the climax, the sacrifice Arthur makes — throwing himself into danger to save his children — reverses the machine rather than powering it. Cyrus is killed by the ghosts he spent his life hunting. The Eye of Hell closes. The glass walls shatter, and the twelve spirits scatter free into the open air.

The family escapes as the house collapses into its underground foundation.
