When the client Ted Garza calls Elise to ask for help since he is haunted since he moved to a house in New Mexico, Elise refuses the request since the address is the same house where she spent her childhood. However she changes her mind and accepts the job, and travels with her assistants Specs and Tucker to New Mexico where they will discover an evil entity in the house.

Did You Know?


In the basement of the house, there hangs a haz-mat suit and gas mask. This same mask is later used in Insidious by Elise (Lin Shaye) and Specs (Leigh Whannel) for transcribing ghost voices. See more »


If Elise's father worked for a prison and the house was on the prison's grounds, it would belong to the state. Even if the state closed the prison, it would still own the property and it would likely close the housing down or demolish it.

It certainly wouldn't sell it with all of the personal furnishings and belongings from 40-50 years ago in the houses. See more »

4 April 2018 | by suganthramSee all my reviews

Insidious 1 is one of my favourite horror movies.Its unfortunate the sequels weren't as good as the original,with each having its own problems.While chapter 2 was spot on in scares,its confusing plot was a let down.In case of Insidious 3,it was the other way around with better writing but poorly executed and predictable scares.As for Insidious 4,it was sloppy in both.The plot was okay till the 1st half of the movie after which it got a little lousy.And the movie had too little scares for a horror movie.Even Joseph Bishara wasn't his usual self this time around with a sub standard scoring.Lin Shaye was the only saving grace of the movie.Overall it is worth a one time watch but it is way below the standards of the Insidious franchise
