 Richard Adams, a former friend who broke with professor Ian Hood after a girl matter, claims to have made the greatest ever discovery in climate change, but behaves paranoiac towards everyone including Hood, encrypts all his findings and has nothing published by the time he disappears. Hood must try to break the code and find out what happened to Adams, who is found dead at a bridge where men commonly jump as a form of suicide. Hood believes to know which powerful interest groups wanted to stop Adams  research being published at any cost.
