Gus Roberts (Nick Frost) is the number one installer at SMYLE, Britain's biggest mobile network operator and internet service provider. In his spare time he's also a keen investigator of the paranormal. Gus is less than pleased when his boss Dave (Simon Pegg) partners him up with new recruit Elton John (Samson Kayo). But then their first job together leads them right to a real life haunting...
Broadband installer by day, paranormal investigator by night, Gus is annoyed to be partnered with "noob" Elton, but comes to appreciate having someone along for the ride as they uncover a spike in supernatural activity. They're soon joined by Astrid (Emma D'Arcy), who has ghost problems of her own, and the gang embark upon creating a ghost-hunting YouTube channel, uncovering a terrifying conspiracy as they go.
