The plot tracks the story of Catalan teacher Antoni Benaiges, destined in 1935 to a small village in the province of Burgos (introducing innovative and inspiring teaching methods from France among the children before being murdered by Falangists during the Civil War), as well as the present-day story of Ariadna, searching for her great-grandfather, who disappeared during the War.[2][3][4][n.

[17] Ekaitz Ortega of HobbyConsolas rated the film with 73 points ('good') highlighting how it "has its own identity, it is not complacent and the two [lead] actors standing out", as the best things about it.

[4] Jason Blake of Limelight rated the film 4 out of 5 stars, deeming it to be "a powerful reminder that the scars of Spain's 20th century history are everywhere".
