In this nail-biting thriller, Paul (Christopher Collet), a bright 16-year-old, discovers that his mother's boyfriend Dr. Mathewson (John Lithgow) is refining plutonium undercover, right in their neighborhood. Intent on exposing the secret weapons factory, Paul steals some plutonium with the help of his girlfriend (Cynthia Nixon) and constructs his own atomic bomb. By the time Dr. Mathewson discovers the plutonium is missing and informs the government, the device is built - but the timer inadvertently turns on, beginning a countdown to nuclear catastrophe. Suspenseful to the last few seconds, this intriguing, provocative story takes its name from the real Manhattan Project in the 1940s that brought about the development of the first nuclear weapon used in World War II.
