Although the picture quality is good, the same cannot be said for the sound track which features relentless irrelevant music, with sound effects and dialogue in thin distorted and compressed mono.
If you remember In a Gadda da Vida by Iron Butterfly from 1968, you will recognise the bass line which appears all through the film. You can hum along as it may help to brighten up the viewing experience.
The plot is extremely simple and hackneyed; the mafia terrorises a town, a brave policeman (the hero) is constrained by his superiors so much as to be ineffective, then the hero recruits relatives of victims, arms them and ambushes mob in one enormous shoot out. That's all folks, end of film.
This is the 70's at its most cheesiest, and with the screeching mono soundtrack is not a good experience.
