He does not remember who he is, so the centaur Chiron, who has raised Jason, reveals him that he is the true heir of Iolcus.

The Argonauts run aground on a strange island in the middle of the ocean that is actually the sea god Poseidon.

The crew make their way to the Isle of Lemnos, an island of warrior women (Amazons), to recover from the experience and repair the ship.

The men pleasure themselves with the women while their ship is repaired (except Orpheus and Atalanta) and Jason sleeps with the queen Hypsipyle.

Atalanta discovers that the women have killed all the men on the island and are planning to sacrifice the crew.

Hercules, Orpheus and Argos sail the ship around the island to make it seem as if they have left while the others hide in the water and then join Jason and Medea.

When the soldiers attack, Medea kills her brother and leads them to the Fleece which is guarded by a dragon.

Some Argonauts are killed before Jason sets a noose around the dragon's neck and makes it fall off a precipice.

Zeus attempts to seduce Medea but she says she loves Jason, even when he pulls out Eros's arrow.

The ship arrives back in Iolcus and Jason learns his mother killed herself, believing him and Acastus to be dead.
