Miren and Bittori have lived side by side in a small Basque town all their lives. Their husbands play cards together, their children play and eventually go out drinking together. The terrorist threat posed by ETA seems to affect them little.
When Bittori’s husband starts receiving threatening letters – demanding money, accusing him of being a police informant – she turns to her friend for help. But Miren’s loyalties are torn: her son has just been recruited as a terrorist and to denounce them would be to condemn her own flesh and blood. Tensions rise, relationships fracture, and events move towards a tragic conclusion . . .
