What happens when a protected predator threatens an endangered prey?  High in California's Sierra Nevada, the last few native bighorn sheep are fighting for survival.  Threats from mountain lions have forced wildlife officials to take extraordinary measures to protect the bighorn.  Two remarkable men stand between the bighorn and extinction.  An oboe-playing mountain man turned consummate scientist finds an unlikely ally:  a mountain lion tracker of skill and instinct — a modern-day frontiersman.
