In 1983, artist Tony Mathias began work on a new installation – a collage of visuals and sounds, exploring the history of the abandoned RAF base on Warden Fell. Tony was a gentle soul, a devoted family man. But after visiting the site to tape-record the sounds there, he killed his wife and children, set their home on fire, and turned his gun on himself. The closest thing to a reason why were two words, scrawled on a fire-blackened wall: WORLD’S END. Decades later, true-crime podcaster Cally Darker begins researching the murders, aided by Tony's actress sister Stella. When she finds Tony’s recordings, she thinks she has a fantastic exclusive – perhaps even a chance to solve the mystery. But Warden Fell, for centuries the focus of folklore, mysteries and fearful legends, has a far older and more terrifying story to tell. Cally’s about to learn what turned Tony Mathias into a killer. But it might be too late to save her. File Under: Can you hear me? | Distortion | Hellishly Loud | Sound Effects
