The dark ages. Mythological Greece is archaic. Navigation is also... Moving away from the coast is a challenge to the gods and nature. Jason and the Argonauts will be the first to have the courage to take off and sail on the high seas. They will go from discovery to adventures and land on the strange island of LEMNOS. Atalante, who has won the right to be the only woman on the crew, will attend and participate in their exploits. While Jason aims to seize the Golden Fleece in Colchide to recover his throne without putting his country to fire and blood; Atalante, she, has other ambitions... But is this not the case of each of the Argonauts, these heroes in personal quests?
