This is a bloody slaughterhouse of a case spanning ten years. An old cop and a young one, both of whom can't stand each other, are forced to work together. Before a copycat killer can dismember the entire city to the rhythm of a musical score, they must dig the real monster out of a pile of long-buried, rotting evidence. He has escaped justice because of everyone's indifference. Otherwise, in the name of justice, the executioner's blade will keep cutting the throats of the innocent.
