Early 20th Century Aotearoa, land and resources are scarce. To secure peace for his tribe, Ngāti Awa Chief Te Ramaapakura anticipates an impending invasion by issuing a challenge to his enemy.

An unwelcome stranger crosses a tribal boundary forcing Ngāti Rangitihi Chief Tionga to react with caution to a possible alliance between bordering tribes.

Uncertainty prevails after a failed attempt on Chief Te Ramaapakura’s life. Ruamahu settles into life with Te Ao and is overwhelmed when she receives an unearthly gift.

A grief stricken Te Ramaapakura ventures into unknown territory. Tionga faces the loss of one of his own while Te Purewa waits for the signal of war from Te Rehu o Tainui.

Te Purewa declares war while Ruamahu is consumed by revenge. Te Huru’s loyalty is questioned and Tionga is lured into a trap.

Ruamahu settles the score as the battle at Pukekaikāhu erupts. Mokonuiārangi must choose between securing peace for his people or all out war.
