The novel is set just before the start of the battle of Troy. The Greek army under King Agamemnon is stuck on the island of Aulis en route to Troy because of a mysterious dying down of the winds. The army is restless and rumor and gossip fly around seeking a reason for the becalming as the men gamble and squabble while they wait and Odysseus connives and schemes behind the scenes with the help of Chasimenos, Agamemnon's chief scribe. The king is slowly convinced that he must sacrifice his daughter Iphigenia for the gods to be satisfied and Iphigenia is brought to Aulis under the pretext that she is to marry Achilles, the Greek hero. Along with her slave, Sisipyla, Iphigenia arrives in Aulis and discovers the plot. Sisipyla offers to take her place but, at the last moment, convinced of her own destiny, Iphigenia sacrifices herself.
