The documentary represents several social groups:
- Males are portrayed as both antagonists who experimented on females causing widespread death, and as a distressed newscaster. This reinforces stereotypes of males being dominant and powerful.
- The female protagonist is both a weak and fragile sole survivor struggling with isolation, but also strong and independent in her ability to survive on her own. This breaks gender stereotypes of females needing male protection.
- The film portrays only white British citizens due to the filmmakers' limited access to actors of other ethnicities.
- Teenagers are the subjects of the film to make the storyline more relatable and engaging for the target teenage audience.
