15 years after pioneering interactive horror in Southern California, Delusion is going back to its roots. The iconic immersive theater experience will return to the historic Beckett Mansion in Los Angeles for its 2026 production, Delusion: Den of the Mosquito.
Pitching its darkest storyline in years, Den of the Mosquito transports audiences to a brothel in 1920s New Orleans for a supernatural tale of crime, family, mobsters and monsters, with vampire courtesans lurking at the center of its mystery.
The plot centers on Anomaly—a secret organization established by President Woodrow Wilson to investigate the paranormal. After a covert operative goes dark inside a bayou brothel run by the local Mafia, his final transmission warns of an ancient power feeding on human blood “like mosquitoes.” Guests are deployed as field agents to investigate, tasked with finding their missing colleague, infiltrating the brothel, and extracting whatever bleeds from the bayou.
Billed as Delusion’s longest and most interactive production to date, the 50-minute experience features branching paths, sadistic lore, and vampire prostitutes. The new production returns to the intimate, character-driven storytelling and close audience interaction that defined Delusion’s earliest seasons. Each performance is limited to a group of 10 guests and unfolds as a streamlined, approximately 50-minute narrative play.
The 2026 season runs on select nights from Sept. 17 through Nov. 8. Tickets start at $143 on select nights and are on sale now. For additional information, including event details and ticketing, visit EnterDelusion.com.
