Frustrated by the high cost of electricity and his sister Missy "wasting" energy on a nightlight, Sheldon decides to build his own nuclear reactor to power the town. He begins collecting americium from hundreds of smoke detectors, a plot point that references a story told by Mary Cooper in The Big Bang Theory . His project eventually draws the attention of government agents.
The episode’s A-plot follows Sheldon (Iain Armitage) as he becomes obsessed with creating a nuclear reactor to power the town, a goal stemming from his reading of the “Radioactive Boy Scout” story.
