Hercules
Hercules (Steve Reeves) walks into the Greek kingdom of Iolcus to tutor King Pelias's son and falls for the king's daughter Iole (Sylva Koscina) before he has unpacked. She is not his to win yet, and the quests that stand between them pull him onto the ship of Jason (Fabrizio Mioni) and the voyage of the Argonauts. Pietro Francisci keeps the demigod and the princess in each other's sights across every sea and trial.
