Dramatizes a fascinating historical episode from the end of World War II. In the summer of 1945, with Hitler defeated but the Pacific War still raging, six of Germany's top nuclear scientists are held by the Allies at Farm Hall, an elegant estate near Cambridge. Among these detainees are three Nobel laureates.

As they wait out their confinement, the scientists occupy themselves with censored newspapers, a malfunctioning piano, and a copy of Noël Coward's play "Blithe Spirit." Their relatively peaceful captivity is suddenly disrupted when news breaks that the United States has accomplished what they could not – the creation and deployment of an atomic bomb against Japan.

Unbeknownst to the German scientists, their entire stay at Farm Hall is being covertly monitored, with every conversation and reaction meticulously recorded. This play draws inspiration from the actual events that unfolded at Farm Hall between July 1945 and January 1946, offering a unique glimpse into a pivotal moment in scientific and military history.
