Three men attempt to kidnap a doctor vacationing in the mountains of Washington state. The doctor falls down a steep hill side. One of the three kidnappers is tracking the doctor while the other two proceed with plans to extort $200,000 from his wife. The FBI gets a break when one of those two is arrested for another crime. Erskine and Colby try to pick up the trail of the doctor. Meanwhile, the physician is playing a desperate game of cat and mouse with the man tracking him.
