The Basque Country, Spain, 1980s. In an atmosphere of tension and fear, where the harassment of separatist nationalism and the violence of ETA terrorist gang are a constant in life, Eloy, a young civil guard from Madrid, arrives at the Intxaurrondo base, in San Sebastián, as a volunteer; a hostile environment that causes havoc among his companions: alcoholism, depression and suicides reign. The so-called “Northern Syndrome” kills as much as bombs do.

Since its birth in 1865, in the wake of the American Civil War, the history of the Ku Klux Klan has been inseparable from that of the United States. The debates over slavery, the populism in the roaring twenties, the struggle for civil rights in the sixties, the rise of the far-right in the early 21st century; the Klan seems to have always embodied the dark side of the nation, with its gray areas and blind spots.
