Nine years after the tragic events of Hell House, the Abaddon Hotel will once again be open to the public. Billionaire Russell Wynn has taken his audience-interactive show, Insomnia, into the abandoned hotel. Russell invites journalist Vanessa Shepherd to film an exclusive behind-the-scenes documentary of the production. What she uncovers will shed light on Russell's true intentions for relocating his show to the Abaddon and the evil waiting to be unleashed.

Picking up a year after Hell House LLC II: The Abaddon Hotel (2018) and nearly a decade after the mysterious tragedy of Hell House LLC (2015), ambitious tech magnate Russell Wynn saves the infamous hotel from the wrecking ball. After all, Russell is confident that his interactive Insomnia Show, a modern take on Faust, will be a big hit. He is unaware, however, that evil never dies. And as young host Vanessa Shepherd and her crew arrive to film a behind-the-scenes episode of Wynn's production, vague, blood-chilling darkness watches their every move. But now, there is no turning back. Who knows what terrors lurk in the Beyond?—Nick Riganas
