In "The Wrong House," a group of five seasoned thieves, led by the resourceful and charismatic Alex, embark on their greatest heist yet: robbing the opulent mansion of the Sinclair family, rumored to have a vast hidden fortune worth around $13 million in cash and gold. As they infiltrate the mansion in the dead of night, they soon discover that the Sinclairs are not your typical wealthy family but members of a sinister satanic cult. Hidden chambers and eerie symbols throughout the mansion hint at the family's dark secrets, and many locals who have gone missing might have met their demise in this house.

The Sinclairs are supposed to be at an elite social event on the night of the robbery, but as the thieves delve deeper into the mansion, they unwittingly disrupt a chilling occult ritual taking place in the heart of the house. This unintentional intrusion triggers a series of catastrophic events as the Sinclair family realizes their home has been invaded. The Sinclairs immediately retaliate, brutally killing two of the thieves and announcing to the others that if they can survive the night, they can keep the fortune.

The Sinclairs transform from prey to predator as they systematically and ruthlessly hunt down the intruders within the sprawling mansion. They use a variety of weapons and enlist other cult members to aid in the pursuit. The Sinclairs are very skilled at hunting people down. The tension escalates as the thieves strive to unearth the hidden fortune while staying one step ahead of the malevolent cult.
