The May 31, 1937, the Andalusian city of Almeria is bombarded by a fleet of four warships and the German pocket battleship "Admiral Scheer". The balance of the German attack on Almería was 40 dead, 150 injured and 200 buildings destroyed. The indiscriminate attack on the civilian population,was comparable to the suffering in Guernica a few days before.
On the 70th anniversary of the most tragic shellfire over Almerias city during the Spanish Civil War, a group of citizens and tourists who were visiting the antiaircraft shelter enabled as a museum, got stuck and isolated inexplicably because of a sequence of events. The disorientation, the fear, and the 4.5 km of warren labyrinthine and claustrophobic tunnels make them revive their worst nightmares.
