Following Basque separatist group ETA’s historic ceasefire, Bittori returns to her hometown demanding answers about her late husband Txato’s unresolved murder.

Bittori is visited by her son Xabier and daughter Nerea, who come bearing surprising news. Meanwhile, though their parents no longer speak, an encounter at the hospital reunites Xabier with Miren and Joxian's daughter Arantxa, providing him an opportunity to return something special from their childhood--and further piquing Miren's suspicions as a result.

With Joxe Mari the subject of a massive police hunt, Miren turns to the only person she can trust--Bittori--but unintentionally divulges Txato's secret in the process. Meanwhile, as Nerea and her friends are confronted by the police, Txato and Bittori navigate the fallout of escalating threats from ETA.

While local resentment towards Txato reaches a fever pitch, Joxe Mari's shadowy ETA superiors enlist him to execute a series of hits. Later, news of Txato's murder breaks, and a devasted Bittori's grief deepens as she's warned against having his funeral in town, while Joxian grapples with the death of his friend from a distance.
