This preposterous post-WWII drama stars Flame the dog as a retired military pooch who lost his beloved master to the murderous hands of a trench-coat wearing Nazi. After the war, Flame was sent to retire in a peaceful hunting lodge. One day, three visitors come to the cabin. One of the suspicious fellows wears a trenchcoat identical to the one the killer war. Overcome by memories, Flame attacks the trio. Later his instincts are proven true when the three are proven to be German spies come to steal information about a nearby nuclear project.
