Tribal Council chairman Walker Chee has discovered a stratum of oil shales in Maskai Canyon, the most sacred ground in the tribes domain. Walker is dynamiting the caves in an effort to unleash oil, and is planning to sell the rights to process them to the tycoon Roger Piggott of Peabody Oil. Walker is desperate to keep word of the attacks from leaking to the media before he completes the deal.Although common sense tells him otherwise, Youngmans faith in tribal beliefs and superstitions leads him to suspect the unexplained deaths may be connected to the spell Abner claimed he cast.

As they spread throughout the area, swarming through a missionary groups campsite and infecting everyone in their path, Philip and Youngman join forces with Anne Dillon, a young white medical student who runs a ramshackle clinic on the reservation and is in love with Youngman, to track the bats to their lair and destroy them. ........
