Josh Lambert drops his son Dalton off at an idyllic university, but Dalton's college dream becomes a nightmare when the repressed demons of his past return to haunt them both. To put their demons to rest once and for all, Josh and Dalton must go deeper into The Further than ever before, facing their family's dark past and a host of new and more horrifying terrors that lurk behind the red door. Patrick Wilson, also making his directorial debut, returns alongside other members of the original Insidious cast - Ty Simpkins, Rose Byrne, Andrew Astor, and Lin Shaye - for the final chilling chapter of the Lambert family's terrifying saga.
