Curitiba is a city in movement, with rhythms and different pulsations, a great composed mosaic for fragments of different colors and sizes, that coexist, however nor always are touched. A city of contrasts, light and darkness, indifference and solidarity, errors and repentances. It's the coldest week on Curitiba's winter. The scenery where faces pass for the windows of the cars and people divide the sidewalk without its looks if cross, that four histories are counted on four men who have their lives transformed when the conscience talk louder than the survival instinct.
