Prokop is a scientist who has a passion for the chemistry of explosives; this passion flowers in the discovery of Krakatit, a new explosive infinitely more powerful than any previously known, an explosive capable of wrecking the world; the small box of Krakatit is stolen; Prokop, in a panic of fear lest his terrible discovery do irreparable harm to humankind, begins frantically to chase what faint clues he has.
