After being attacked by four sword-wielding bounty hunters, Xena (Lucy Lawless) saves the life of Demophon (Russell Gowers), one of the attackers who has been badly wounded in the fight, and waits out a terrible storm with her captive and Gabrielle (Renee O'Connor) in a local tavern. When both Demophon and a loudly coughing customer in the bar suddenly die -- and a man's howling scream is he ard over the sound of the thunder -- Xena realizes that Prometheus (John Freeman) has been captured by the gods. Gabrielle explains to the innkeeper that according to legend, if Prometheus is ever bound, mankind will lose all the gifts he gave them, including fire and the ability to heal themselves. Determined to free Prometheus, Xena consults the oracle Io (Jodie Dorday) and is put through a series of dangerous trials to prove how much she is willing to sacrifice. After passing the tests, Io tells her she must go to Vulcan Mountain and enter the cave of Hephaestus where she will find the only sword that can break the chains that bind Prometheus. Io warns her, however, that warriors loyal to the Temple of Hera will stop at nothing to keep her from her mission. Xena accepts the challenge.
Xena enters the cave and is immediately pursued by a number of Hera's fiercest soldiers armed with broadswords and battle axes. As she flees deeper into the cave, she must also evade spikes popping out of the cave floor and giant hammers swinging down from the ceiling like deadly pendulums. Finally, she reaches the Sword of Hephaestus which is embedded in a large stone, and with a mighty heave, she pulls it free. Emerging from the cave, Xena is surprised when Hercules (Kevin Sorbo) suddenly appears and asks her to hand over the sword. She charges him with a fallen branch and after a flurry of skillfully parried kicks and blows, she flees on horseback.
Later, as Hercules and his friend Iolaus (Michael Hurst) help her fend off another ferocious attack by Hera's soldiers, it becomes clear why Xena avoided Hercules: whoever wields the sword to strike the blow that frees Prometheus will be destroyed. Each will not allow the other to complete the suicide mission but for the moment, they agree to work together. On the way to the mountain where the chained Prometheus is dangerously close to being devoured by a giant eagle, Hercules and Xena rekindle their deep friendship. Gabrielle and Iolaus are also very drawn to each other. When Gabrielle discovers that he has been hiding a wound he received during the battle with Hera's soldiers, Iolaus bravely asks her not to mention it to Hercules and Xena since there's nothing they can do for him until Prometheus is freed.
As the foursome make their way upwards through the cavern inside Prometheus' mountain, Hercules reveals that he had been here long ago with his father, Zeus. Xena and Hercules realize Iolaus has been wounded when he is further weakened in a sudden cave-in. Knowing Iolaus will not survive the climb, Gabrielle remains behind with him as Hercules and Xena continue on together. In the end, the two join forces to free Prometheus by battling a horde of lizard men who have hatched from huge eggs encircling the god's chained body, as well as the gargantuan eagle which captures Xena in its claws. In the process, they manage to avoid direct contact with the hurled Sword of Hephaestus which severs Prometheus' chains, so both are able to survive the ordeal. With Prometheus free and his gifts to mankind restored, the four friends bid each other a sad farewell, though its seems certain they will meet again.
