After a sinister cult conjures evil spirits in their new home, a young family must survive the demonic presence and the cult that’s hell-bent on sacrificing them to ancient deities on Halloween night.

What's new or different about it? Not asking sarcastically. Is it more character-driven than the average horror? What?

As stories are told within a finite amount of time, you need to describe the start and end point of the plot.

Define their goal with a specific objective - survival is an on going activity that can last from a few hours to a few days. What one specific achievement says, beyond a doubt, that they've succeeded in surviving?

Make 'an atheist family' sign up a blood contract with a conceited Halloween cult---in an attempt to annoy them by stealing their magic lamp (which was meant to be buried by the sunrise)---accidentally releasing evil spirits in their pool party, and now MUST contact the cult HQ for a possible solution....
