[citation needed] The film begins with the alien abduction on Scalleum, a remote island off the coast of Wales, of Cat Williams and her boyfriend.

Cat's story attracts the attention of Michelle "Foxy" Fox, the bosomy host of the cable TV show Weird Worlde, who brings a film crew to the island — her cameraman boyfriend Ricky; Jack the sound man; nerdy UFO expert Gavin Gorman; and actors Bruce Barton and Candy Vixen (the latter, Foxy's producer assures her, "because she's good, not because she's my girlfriend").

The Weird Worlde crew sets out in their van, but it is dark by the time they reach the Williams family's creepy farmhouse, where they meet Cat and her three hulking and sadistic brothers (who speak only Welsh with English subtitles).

Jack the sound man, meanwhile, having been blinded by alien ichor early in the film, swims across the channel to the mainland, only to discover that he's lost the videotape that was the only proof of their extraterrestrial encounter.

The film features an ensemble cast including TV presenter Emily Booth, Jamie Honeybourne, Christopher Adamson, Norman Lovett, Scott Joseph, model Jodie Shaw, and Jennifer Evans.
