It is the largest load he has ever brought down from the mountains and he wonders how Carson will smuggle it into the U.S. Carson tells him he has one man in mind but that this would be his last shipment. After that, he intends to retire in luxury. Ranagavana is interested in meeting the man who would be responsible for bringing the drugs in. Perhaps he could go into business with him after Carson's retirement. But Rangavana doesn't get the chance. Carson and his men massacre the General and his troops.
