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).
