On the cusp of the Spanish Civil War in a coastal village in the Basque country, three men stop off at Extarri's bar on their way to a wedding. There, a bizarre and seemingly incidental event marks the beginning of a powerful story about a bond and a secret that endures even in death.

Abandoned by her parents shortly after the outbreak of war, sixteen-year-old María Antonia Extarri is left at the mercy of the soldiers. Meanwhile, Isabel enjoys a blissful honeymoon, but just a few months later her valiant Captain is shot as a traitor. Both María and Isabel suddenly find themselves violently altered, alone, and pregnant. A crippled young doctor is the only witness to the mysterious agreement silently formed between the two desperate women.
