A present day pipe bombing shows similar characteristics to three prior pipe bombings all of which took place in the last nine years. The evidence is lacking with two dead victims and two critically maimed who share no common denominator. The bomb device turns out to be a music box that plays the song "John Henry", an American song standard about man versus machine, leading the detectives to believe the bomber may be anti-establishment. After a lead brings them to what they believe may be the bomber's apartment they discover pictures of all the victims. However, one picture proves the bomber in his latest attempt missed his intended target. Putting that man under protection the detectives slowly start to figure who the mysterious bomber may be after interviewing the surviving victims. The bomber, a man who had lost his home, his job and his family slowly spiraled out of control. Feeling abandoned by the establishment and his own brother who he felt had turned against him and the legacy of their family's home where they grew up by not stopping it from being torn down, he decides to take what his brother loves most and plants a bomb in his brother's home. But the detectives manage to figure out what he was up to and save the family from the explosion.
