Pandora's Box

Kyros, a vicious money lender to whom Hercules is in debt abducts Medusa and will only release her if Hercules and Jason bring him a box from Hades, the Underworld. Advised by Eunapius, a former servant of the Underworld goddess Persephone enter Hades and obtain the box but are warned that if opened it will bring bad luck upon mankind. Jason devises a plan to free Medusa by tricking Kyros with a duplicate box but unfortunately Medusa's curiosity gets the better of her and she opens the box.
