During the height of the Cold War, the U.S. built one of its most secretive military projects beneath Greenland’s Ice: Camp Century. Officially presented as a science station in 1959, it was part of the covert Project Iceworm – a plan to deploy nuclear missiles close to the Soviet Union. More than 200 soldiers lived and worked beneath the Arctic surface, powered by a nuclear reactor in tunnels stretching for miles. Abandoned in 1966, Camp Century left behind tons of nuclear waste. Today, that legacy is thawing as the ice melts. With firsthand accounts and declassified footage, this documentary reveals a buried city, a Cold War gamble, and an environmental time bomb reawakening in a warming world.
