Two crop-dusting pilots who worked for orange grower Clint Carpenter have vanished without a trace. Joe Mannix is asked by his former military buddy, Dave Winters, who runs the crop-dusting service, to help solve the mystery of their disappearance. Mannix returns to the California farmland of his youth posing as a new pilot, but soon finds himself in the middle of a feud between his client and the local Armenian farm workers - whose leader claims that he and his people were cheated out of the land Carpenter now cultivates.
