The city of Athens has been struck by plague. The priestesses at the temple of Athena have determined that the plague is caused by the god Apollo, who has grown angry at the city for some unknown reason, and the way to avert his wrath is the Oracle of Delphi.
The first expedition sent to Delphi by the temple did not return. Now it is the turn of the heroes – descendants of the gods, with remarkable talents arising from their divine ancestry – to save Athena’s city.
