Insidious: The Red Door is the fifth installment in the horror franchise and centers around the original characters. While the third and fourth movies do not focus on the Lambert family, The Red Door continues their story and picks up a decade after the events of Insidious: Chapter 2. Dalton, who's lost all memory of his time in The Further, heads to college following his parents' divorce. However, the past begins to come to light, and both Dalton and his father realize they are being haunted by a demonic presence.
