Numitor, King of Alba Longa, is forced into exile by a prophesy. His throne goes to his grandchildren, Iemos and Enitos, but someone is scheming. Wiros, a slave in Velia, is in the woods for the Lupercalia. The Vestal Ilia hides a secret.

Ertas, King of the Gabi, does not trust Amulius' words. Ilia hears some news and decides to change her fate. Iemos is in the woods with the Luperci, where he meets Wiros for the first time.

Ilia visits the priest of Mars, starting her transformation. Back from the woods, Wiros tells the others that he ran from the goddess of wolves, but Iemos is the only one who can save him.

Iemos and Wiros venture in the woods teeming with eerie creatures on their way to Gabi. Ilia continues her training, while Numitor and Silvia, arrived in Ertas, try to convince the town's Sages that Amulius lied to them.

The Ruminales take Wiros e Iemos to the cave to meet the She-Wolf. Ilia takes off with her father, Amulius to seek justice. Numitor e Silvia leave the city with Prince Lausus.

The soldiers of Velia walk into the woods looking for the Ruminales, who have been waiting for them with Iemos and Wiros, ready to fight. Eager for vengeance, Spurius sets fire to the woods. Amulius must return to Alba Longa.
