Truth Seekers - Season 1 Episode 2

Gus and Elton are sent to fix the broadband connection at The Portland Beacon, "the only horror themed hotel on Dorset's Jurassic Coast". Just as Gus is beginning to tire of the eccentric owners and their daft horror gimmicks, Elton stumbles into the mysterious Room 2, and then a passageway to a secret bunker beyond. It's there that they find the very surprising cause of the problem with the signal.
