It was always speculated that in between the heavens and the mortal plane is where limbo resides. It was also assumed that there is another layer above limbo where time is treated quite differently. A plane of existence known as "The Further" where those who don't move on to the heavens have a chance of ending up there. And in The Further resides those who want to get out, by ruining someone's life and taking it for themselves. Some wish to trap spirits in The Further for all eternity and enslave them. But soon specific spirits and demons will attack the mortal plane with an Insidious agenda......

Based on the Insidious Franchise
