Hercules liberates the giant Typhon, whom Hera magically trapped in a rock for over a century, earning a good natured friend. Only later they learn Echidna is Typhon's wife viz. their children were slain by Hercules. Thracian warlord Maecius hears of the death of brother Demetrius and tortures Iolaus, forcing him to lead his mercenaries to Hercules, who must be lured to caved-in Echidna after she and Typhon are stirred against him, but that's counting without the giant and the hero's pacific nobility.
