The plot concerns a group of friends who meet at a cafeteria and discuss population reduction conspiracy theories. One scene and features Ernest explaining how a bio-engineered virus and fake science could be used to reduce the population by 95%. Ernest suggest "mass genocide on a scale never seen before, there are a mass of ways to introduce population slaughter, staged events...use of bio-engineered diseases. Not this generation but the next." Dion replies "That's madness!" To which Ernest replies (with Mayall's characteristic, quick wit and final joke) "You're right, they would never wait two generations."

Rik Mayall died from a sudden heart attack after jogging in June 2014, 5 months after the film's release.^[6][7]
