In modern-day Britain, most of the superheroes of the 1960's and 1970's have been locked away in a mental asylum, with the public long believing them to be mere fiction. Penny, the daughter of one of the inmates, seeks to change this.
This miniseries contains examples of:
- The Big Guy: Captain Hurricane is a huge strongman.
- Cerebus Retcon: Most notably with Captain Hurricane and Grimly Feendish.
- In the original comics, Hurricane was a heroic soldier with super strength who helped fight the Germans during WW2. Albion reveals that he's actually the only survivor of a Super Soldier experiment, which turned him into a superhuman psychopath who butchered countless enemy soldiers with his bare hands in a berserker rage (a reference to the original character getting super strong when he got angry).
- Grimly Feendish originated from the humor comic strip Eagle Eye, Junior Spy, where he was known as "The Rottenest Crook In the World" (and very similar to Uncle Fester from The Addams Family) . Albion changes the comical portrayal of his ghoulish behavior, and shows him to be a mass murderer and psychopath who traumatized his underage nemesis.
- Deliberate Values Dissonance: Captain Hurricane is casually racist.
- Fat Bastard: Grimly Feendish, he'd give The Blob a run for his money.
- It's Personal: Heavily implied between Eagle-Eye, the warden of the asylum, and Feendish, who had been his arch nemesis in the days of Eagle Eye, Junior Spy. The trauma Feendish caused him as a child hero is implied to be the reason why Eagle Eye helped imprison all other costumed people.
- The Masquerade: The Thatcher government had everyone with superhuman abilities or otherwise extraordinary tendencies rounded up and locked away because they didnt want anyone disrupting the rigid society of Conservative Britain.
- The Quisling: Jason Hyde, "The Man With the X-Ray Eyes", works as a security guard in the asylum, helping to keep his former allies locked away.
- Ungrateful Bastard: Back in the 80's, The Spider agreed to help Margaret Thatcher's government round up every superhero and supervillain, as well as anyone else with powers who might have disrupted the Tories' plans, which he did. As a reward, he ended up being locked up, too.
