Andromeda, the daughter of King Cepheus, longs to be a warrior in her father's army, but women are not allowed to fight, and so the king forbids her. Instead, the king obliges the Queen's wishes to marry Andromeda off to a wealthy prince. Desperate to make her dream come true, Andromeda appeals to the goddess Athena, who gives her a spectacular suit of armor to hide her identity. Now disguised as the 'Silver Warrior,' Andromeda challenges the best warriors in the kingdom and beats them all until she meets the hero Perseus and falls in love with him. However, conflicts of love are nothing compared to conflicts with the gods. When the Queen brags that Andromeda is more beautiful than Poseidon's daughters, the sea god unleashes the sea monster Cetus upon the kingdom. Only the Silver Warrior is brave enough to fight the beast. With the help of Perseus, she defeats the monster. The Silver Warrior reveals his true identity and when the king sees that it's his daughter who has saved the kingdom, he is more than glad to have his warrior princess in his army.
