A hero is trapped in some location or situation (aka the “house”) and must survive a monster (human or otherwise). There must be a sin committed—often greed—prompting the creation of a supernatural being that comes like an avenging angel to kill the sinners. Monster in the House stories are commonly found in horror movies, urban thrillers, or comedies about people or things that just won’t go away.
The 3 elements of a MONSTER IN THE HOUSE story are:
1) A monster that is supernatural in its powers—even if its strength derives from insanity—and “evil” at its core. 2) A house, meaning an enclosed space that can include a family unit, an entire town, or even “the world.” 3) A sin. Someone is guilty of bringing the monster in the house… a transgression that can include ignorance.
