London, England, 1952. 

Meet the mercurial genius Professor Quanderhorn (James Fleet) - a maverick scientist with absolutely no moral compass. Join him and his rag-tag crew on their frontal-lobe-knotting escapades as they: 

• Battle insane hybrid creatures: the Gorrirrel and the Squirrilla, to the death!
• Become gods to a Stone-Age tribe
• Are engulfed in a Martian invasion of Earth
• Escape shipwreck on the Moon in a spacecraft powered by anger
• Evade multiple fiendish traps in the Alien Ziggurat of Death
• Tussle with a top-secret parrot
• Become terminally confused when they encounter their past selves in a time accident....

Will our crew of Brave Boffins survive? 

And what a crew they are: Q's part insect son, Troy, reputedly a 'major breakthrough in Artificial Stupidity' (Freddie Fox); eager young test pilot and recovering amnesiac, Brian Nylon (Ryan Sampson); brilliant scientist Dr Gemini Janussen with her half-clockwork brain (Cassie Layton); captured Martian hostage Guuuurk (Kevin Eldon); sinister janitor Jenkins (John Sessions); and synthetic-voice-commentator-later-inserted-into-diving-suit, Dolores (Rachel Atkins). 

Plug in your blue and red cardboard airpods, and pair your tin foil router with the Droitwich transmitter array for an adventure beyond human understanding.
