Princess Verbina and Prince Astor of the Lebidoptirans are on a quest to find their star navy to save their home world Chrystalis. But they are forced to crash land on Aku's Earth and are immediately captured by his minions. Luckily Samurai Jack is witness to the events and follows them.

Summer: while crossing a desert, Jack is attacked by a mirage which takes the shape of a living sand storm. Fall: an evil scientist collects fallen leaves and flowers to brew a deadly poison and put it in a well. Winter: a tribe of ogres forge the ultimate sword using fire and ice, then wage battle to determine the one destined to wield it. Spring: Jack is tempted to take a rest from his quest by a seductive wood nymph.
