Research on Plots

Most stereotypical plots to horror films have a damsel or group in distress and they either work out a puzzle or why something is happening to them and then they try and stop this from happening. They would usually try stop this from happening by either doing what the offender says or by running but either way, stereotypically something bad happens to at least on character throughout the film.

Saw - Perfect example, a group of people who have done wrong in the past are captured and taken to an abandoned warehouse where they will play 'games' to stay alive and people die at nearly every room in the series of 'games'.

Paranormal Activity - A couple have recently moved into a new house and bad things begin to happen relating to paranormal activity. One of the couple starts to get possessed and then results to violence towards the male out of the couple and kills him. But depending on what ending you have seen, the woman either gets shot, walks away or abnormally leaps towards the camera.
