A Soviet rocket falls back to Earth carrying deadly bacteria. KGB Professor Voronov turns the extraterrestrial threat into a terrifying weapon that could be used to devastate the Western world–but he doesn’t take into account the vigilance of Her Majesty’s intelligence services. Soon, Blake and Mortimer are drawn into a lethal, shadowy war, from Moscow to London, where the stakes are no less than international peace and the real enemy may not be so obvious.

When Soviet professor Voronov turns a deadly alien bacteria into a terrifying weapon that could be used to devastate the Western world, agents Blake and Mortimer are drawn into a lethal, shadowy war to defeat him.

Blake and Mortimer head to the United States to investigate the mysterious circumstances surrounding the discovery of a 177-year-old body, which appears to have died very recently. The body is that of a Scottish major, Mortimer’s forebear, who was leading a British military expedition to the US in 1777, where he was swallowed up by a strange multi-coloured light-beam shining down from the sky. Blake and Mortimer fight men in black armed with green-laser guns and soldiers emerging from the past in order to save the Earth from complete obliteration.
