A young woman who found the phone Bailey Dawson used to record her videos in I'm Haunted 2 begins an investigation into the entity known as Cyr and the strange events occurring around it.

The cast and crew of the I'm Haunted movie series discover that the evil entity Cyr from their films is no longer just a character - it has crossed into reality to haunt them for real.

In an effort to escape his past and sober up, a man hides away at a remote property, unknowingly checking into the Glass family's haunted house from I'm Haunted 3.

A woman who watched the Genesis Brady videos from the first I'm Haunted movie attempts to summon the same entity herself to determine whether or not it was a hoax.
