Tagon, the Arthdal Union leader's son, has been tasked with hunting down the Neanthal tribe who are considered to be the 'enemies' of the Arthdal Union. Meanwhile, Eunseom, a member of the Wahan tribe, comes across a village of the Neanthal tribe, where he sees a girl, Tanya, who he believes is the same person he saw in his visions. As Eunseom is about to leave the village, he is discovered by Tagon and his army.
