The Manhattan Project (1986)

Dr. John Mathewson discovers a new process for refining plutonium to purities greater than 99.997 percent. The United States government provides him a laboratory located in Ithaca, New York, masked as a medical company. John moves to Ithaca and meets real estate agent Elizabeth Stephens while searching for an apartment. He attempts to win the affections of the single mother by inviting her teenage son Paul to take a tour of the lab. John is confident in the lab’s cover story but Paul, an unusually gifted student with a passion for science, becomes suspicious when he discovers a statistically impossible patch of five-leaf clover on the grounds.

Paul and his aspiring journalist girlfriend, Jenny Anderman, decide to expose the weapons factory to the media, stealing a container of plutonium as evidence. Once they succeed, Paul declares that the plutonium alone is insufficient, as no-one would be impressed by two kids stealing something from a lab. Instead, he convinces Jenny he can create the world’s first privately-built nuclear device, exposing the lab to the world by audaciously entering it into the New York Science Fair. After convincing his mother and his school that his project is about hamsters bred in darkness, he begins research and construction of the bomb.
