In the early 90s, after the collapse of Soviet Communism, rumours began to circulate about a new weapons technology using a mysterious substance called ‘Red Mercury’. It was believed that small quantities of this material could trigger a fusion device, like a neutron bomb.

Filmed in the Soviet Union, South Africa, the United States and continental Europe, the documentary pieced together evidence that ‘Red Mercury’ was in fact used as a weapons technology.

This testimony was supported by Sam Cohen (1921-2010), the American physicist and inventor of the neutron bomb. Trail of Red Mercury and Pocket Neutron were shown in the UK on Channel 4’s Dispatches, and in Germany on ARD.
