Hercules is given a series of challenges each one was designed tougher by the other by his stepmother Hera.
A series of labors are shown like the slaying of the Lernaean Hydra, catching the stag of Artemis, the Cathmanian boar, the Cretan bull, cleaning the Augeean stables, getting the girdle of Hippolyte, the man-eating mares of Diomedes and the Cattle of Geryon (but the monster is not shown).
