Uranium powers nearly every nuclear plant now marketed across Europe as a climate solution, and this film follows the element from ground to reactor to ask what that dependence actually costs. The trail leads to Australia, home to the world's largest known uranium deposits, where the film examines the mining operations that extract it and the waste left behind once it is processed. Alongside uranium, the film brings in plutonium, typically used in combination with it, and thorium, whose only operating reactor worldwide runs in India. Nuclear fusion gets a brief mention as a hypothetical alternative fuel path using deuterium and tritium, but the film keeps returning to uranium as the fuel actually in use today, and to the risks that come with it. Rather than attempting a full survey of nuclear power, it stays narrowly focused on this one element, tracing its mining, its byproducts, and its central, unresolved place in any argument for nuclear energy as a climate fix.
