When Jason learns of Ariadne's betrothal to Heptarian, he is brokenhearted. With nothing to lose and everything to gain, he enters into a brutal fighting tournament to honour the nuptials - lining up with a bevy of terrifying contestants including the undefeated Heptarian. Determined to beat the husband-to-be and show his worthiness, it is up to Jason's loyal friends to guide him through the contest, where there are more than just broken hearts at stake.

The romantic atmosphere beween Hercules and Medusa does not last long as Medusa is abruptly kidnapped by a cruel moneylender, Kyros. In exchange for Medusa's life, Kyros demands that Hercules retrieves a precious and powerful artefact from the Underworld - a task that would mean certain death.

Hercules and his loyal friends face a race against time. Unless they find a way to descend to Hades and return with the artefact, they will be forced to walk among the dead forever.
