The daughter of a grifter--who often plays parts in his amazing shows--must help Prometheus escape from Eden City before he is found and killed by the Avenger, a giant bird that does the bidding of Zeus.

When their clever ruse is exposed, Sam and his mother, swindlers who are selling "miracle" cures to the people of Eden City, find an unlikely ally in Zeus who, in return for rescuing them from an angry mob, needs their help in settling a score with the monsters of Greek mythology.
