A father and son must confront the lingering horrors of the past when a mysterious door to another realm is reopened.

The story

In 2019, nine years after his possession, Josh Lambert's memories of his experience in The Further have been repressed. He is divorced from his wife Renai and his mother Lorraine has recently died. His relationship with his son Dalton, who is now 19, has become strained and unpleasant. While Dalton attends his first art class, he begins to draw a mysterious red door. Simultaneously, Josh begins being haunted by the spirit of a man he believed abandoned his family. As the two men navigate their fractured lives, they are both drawn toward the supernatural forces that once tore their family apart, forcing them to confront the truth of the past.

Full plot (contains spoilers)

In 2019, Josh Lambert lives a fractured life, haunted by repressed memories of a past possession. His relationship with his 19-year-old son, Dalton, is strained. While Dalton attends art school, he draws a red door—the gateway to 'The Further.' Josh is haunted by the spirit of his father, Ben, whom he believed abandoned them. Dalton attends a party where he sees a ghost and, after a mishap, finds himself in The Further. His friend Chris is attacked by a red-faced demon. Dalton calls his brother, Foster, whose memories of a past trauma help Dalton realize the danger. Dalton is pulled into The Further, where he faces the demon and a vision of his father. Meanwhile, Josh learns from his ex-wife, Renai, that his father also had the ability to project and was institutionalized. Renai and Josh enter The Further to rescue Dalton. They find him trapped; the demon possesses him to attack Chris. Josh manages to free Dalton, and they flee toward the red door. Josh stays behind to hold the door shut, allowing Dalton to escape. Dalton returns to the living world and paints over his drawing, sealing the door. Josh meets his father's spirit and eventually reconciles with Dalton, while a post-credits scene shows the door's light flickering back on.
