Juanito, a boy passionate about cinema, finds refuge in movies while the Spanish Civil War tears his world apart. The son of pacifist parents, he grows up in a home marked by ideals of peace and the daily struggle against poverty and his mother's illness. Along the way, he forges a bond with international brigadistas who also share his love for the seventh art. But the reality of the conflict forces him to make a difficult decision that will transform his life, closing the doors to childhood and leading him toward a maturity marked by pain and learning, where cinema remains his beacon in the darkness.
