Join entertainment reporter Billy Bush in an awe-inspiring adventure as he takes time off from his day job to fight illegal poaching of greater one-horned rhinos. He'll accompany poaching patrols; fly an unmanned aerial drone; and participate in a race-against-time effort to catch, collar and release a wild adult rhino. Greater one-horned rhinos are being poached, even within the borders of protected national parks guarded by armed rangers. Just over 500 of these 12-foot-long, 3-ton living tanks survive in Nepal to this day, and their numbers are threatened due to poachers who are willing to profit at the rhinos' expense. A single rhino horn can fetch more than $30,000 on the black market, which is reason enough for poachers to slaughter this rare, beautiful and powerful species. "We have an opportunity to do something really remarkable, and that is to raise some awareness. Most people I told about this mission said, 'there's rhinos in Nepal?'" said Bush
