An ace at extinguishing oil-field blazes, John R. Ingram now battles a personal inferno of his own. A fugitive after a false robbery conviction, the now-respectable Oklahoma family man sees his life and livelihood go up in smoke after a deceitful ex-shipmate re-enters his life, reveals his secret past, swindles him out of his new oil venture and causes him to be sent back to the living hell of the Georgia chain gang, where the guard from whom he escaped the first time is waiting for him.
