January 21st 1968. An American B-52 bomber carrying nuclear warheads has just crashed on the polar ice near the US military air base in Danish controlled Thule, Greenland. A few days later, the US government classifies the crash as a "Broken Arrow" scenario (nuclear accident) but proclaims the situation as under control and no cause for concern in relation to radioactive contamination or violation of a foreign power’s sovereignty. Hundreds of Thule workers are set to work, helping in the gigantic clean-up operation. After eight months, all traces of the crashed aircraft and the plutonium-contaminated snow are gone. The case is closed. 18 years on, while covering a local worker's compensation story, reporter Poul Brink, suddenly runs into suspicious circumstances linking back to the concealed nuclear accident. Apparently, the full and true story about the crash lays well-protected, deep under the ice cap and deep down in the classified archives in the US. The ambitious reporter launches an uncompromising investigation. The deeper he goes, the further he finds himself inside the heart of an international cover-up so immense in size that it holds two nations across the Atlantic culpable. Soon, those in charge are finding it hard to keep the truth about the tragic accident under wraps and will take any measure to suppress Brink.
