When young Dalton Lambert falls into an unexplained coma, his parents are told that he has been astral travelling in his sleep and, unafraid of what he believes are dreams, has wandered too far into a realm called The Further, home to tormented shades of the dead. Only his father Josh, who possesses the same ability of astral travel, can free Dalton, but at what cost?

Husband-and-wife Josh and Renai Lambert seek to uncover the secret that has left them dangerously connected to the spirit world.

Three years before the haunting in Insidious, demonologist Elisa Rainier reluctantly agrees to help a teenage girl make contact with her late mother.
