In the aftermath of Hitler's aerial attack on the Basque Country, the Aguirre family are torn apart. The desperate parents send their two young sons, Mikel and Gorka, on a refugee ship to England, never to see them again.
Struggling to make his way in a new life, Mikel develops a passion for guitar making. He falls in love, and before he knows it, his son, Javier, is born. Impoverished, and now with a family to support, Mikel has nowhere to turn - until an unexpected offer sees him recruited into the British Intelligence Service. Returning in secret to his homeland, his life is suddenly overturned. Will he find his way back home? Will he be reunited with his wife and his son?
A passion for music, and a son's longing for the father he never knew, lie at the heart of the story.
