When Hercules visits his mother, stepfather Jason and family tombs in his native Thebes, Hera strikes it with lightning and a fire-breathing enforcer, which ends up killing Iolaus while he rushes to warn Hercules of her lethal mission. Aided by grateful Persephone, Hercules gets permission to retrieve his mate from the underworld if he can eliminate the enforcer before sunset and is given an outdated enforcer as unwanted, yet as it turns out useful, helper. meanwhile Iolaus meets his father Skouros, whom he despises for leaving his mother and him, and comes to terms with his military careerist past.
