Genius or madman? The adventure film of the year takes us on a bumpy journey to the Siberian steppes, where a Russian geophysicist wants to restore the ecosystems of the Ice Age through radical rewilding.


In the mid 90’s eccentric Russian scientist Sergey Zimov made the startling discovery that melting arctic permafrost threatened to release huge amounts of CO2 into the atmosphere, potentially creating a feedback loop that will lead to runaway climate change. Impatient with world’s slow reaction to this news Zimov has single handedly begun a controversial plan to mitigate melting permafrost by reverse engineering the ‘Mammoth Steppe’ ecosystem – a now vanished ice age grassland, complete with Serengeti-like herds of roaming herbivores, which once stretched from Spain to Canada.
