Summary of Paranormal acticity movies?

This is a very basic summary I wrote In a previous post a few months ago...hope it helps.

Paranormal activity 1 occurs in 2006 and shows us a couple being haunted, eventually leading up to Katie being possessed by a demon. 

Paranormal activity 2 also occurs in 2006, set one month before the first film, where we see Katies sister Kristi her partner Daniel and step daughter Ali being haunted by the same demon who we find out wants their new born son Hunter. We learn that Katie and Kristis grandma Lois, may be a witch, and may have made a pact with a demon, where the demon is promised the first born male of the family in return for wealth and power. 

The film leads upto the events of the first one, where the family eventually perform a ritual to get rid of the demon because it has now possessed Kristi, the ritual can only send the demon to another family member, they chose Katie, which explains why the demon was haunting Katie in the first one, after they perform the ritual the film then cuts directly after the events of the first one on the same night, and we see Katie kidnaps Hunter. 

Paranormal activity 3 occurs in 1988 when Katie and Kristi are only young and we see that this demon has been haunting this family for years waiting for a first born male of the family. We learn that the Grandma is actually a witch and is part of a coven. 

Paranormal activity 4 occurs in 2011 and we see a now 6 year old hunter who we find has been adopted by a new family and has a new name, Wyatt. He was put up for adoption by Katie and the coven presumably to hide from police in an innocent unsuspecting family until the time is right and he is of age for them to perform a first ritual on him. Now we see the time is right for Katie to get him back so they can perform a first ritual on him and the film leads up to this, while throughout he has robbie who is pretending to be Katies son who lives over the road who is guiding him and preparing him for this ritual. We learn the coven is still active and has grown considerably. 

Paranormal activity the marked ones occurs in 2012 and follows Jesse who has just turned 18, who is going through some sort of possession. We learn that he was marked for possession from birth just like Hunter, and now he is 18 he is going through the final stages of possession and is ready for his final ritual. He too had a first ritual at 6 just like Hunter.

In the film we also learn that there is a door that the coven can use to sort of teleport themselves, but you can only go to unholy places. At the end Jesse has been taken to grandma Lois' house from the third one for his final ritual, where Hector and Marisol have gone to find him. While they're there a demonic Jesse chases Hector into a room. In the room there is one of them doors that can teleport you to an unholy place, Hector runs through it and goes back in time to 2006 to Katies house on the night she murdered Micah.
