When news reaches Pasiphae of Ariadne and Jason's impending marriage, she is terrified that Atlantis will be lost to her forever and resolves to do all she can to stop the union, no matter the cost.

Jason has been sentenced to death for killing the Oracle and it looks like there is anything anybody can do to save him including Ariadne. Pasiphae tightens her grip over Atlantis and the future does not look good.

Pasiphae realises she will never be true ruler while ever she and Ariadne both have a claim to the throne, so she offers the queen her freedom – if she will renounce the crown. As wanted men, Jason and Hercules have been forced to seek refuge in the mountains, where Medusa and Pythagoras come up with their own plot, which will take a sacrifice of unimaginable proportions.
