The next day, a wealthy industrialist named Samuel Graynamore makes Joe an unexpected proposition. Graynamore needs "bubaru", a mineral essential for manufacturing superconductors. There are deposits of it on the tiny Pacific island of Waponi Woo, but the resident Waponis will only let him mine it if he solves a problem for them. They believe that the fire god of the volcano on their island must be appeased by a voluntary human sacrifice once every century, but none of them are willing to volunteer this time around. Graynamore offers to pay for whatever Joe wants to enjoy his final days, as long as he jumps into the volcano within 20 days. With nothing to lose, Joe accepts.
