Earth has been conquered by robots from a distant galaxy. Survivors are confined to their houses and must wear electronic implants, risking incineration by robot sentries if they venture outside.
The robot's cube shaped spaceships is a plausible nod to the Borg Cubes in Star Trek: The Next Generation (1987) and Star Trek: First Contact (1996). The Borg Cubes are spaceships and The Borg are cyborg creatures.
When Nathan finds the case of Zippo classic wind proof lighters in the train museum shop, he immediately tests it out and strikes a flame. This is not possible as Zippo lighters are shipped without fuel, one must add fuel after purchasing the lighter.
