During the rise of Nazi Germany, Hagen Messer joins the Royal Air Force as an American soldier who specializes in tracking. He's attached to British commandos and given a seemingly simple mission-to find a captive and destroy a dam-but everything goes awry. Hagen's plane crashes into Germany's Wehr Forest and he has to use his extrasensory abilities to track the captive to nearby Wehr Wolff Castle, a secret Nazi base where vile experiments are being conducted. Hagen and his surviving team members must sneak into the castle and devise a way to destroy the experimental labs creating diabolical creatures. Hagen is horrified to find Nazis and scientists with no scruples, and at the most inconvenient time, he learns that he may be in love with one of his teammates, an Irishman named Liam. In order to protect his love and his friends, Hagen must feign nonchalance amidst pure degeneracy and suspicion. Hagen soon discovers, though, that he is in over his head. What may not only redeem him, but also save his lover and friends, is a childhood past and a darkness lurking deep inside him, just waiting to be engaged.
