Police Commissioner Verrazzano (Luc Merenda) is asked to investigate the death of a man originally ruled a suicide. The dead man's sister (Janet Agren) is convinced that someone murdered her brother. Soon after his investigation begins, Verrazzono's begins to suspect there might be something to the woman's story. It's obvious that someone doesn't want Verrazzono to find the truth, and after investigation, a secret world of loan sharks and organised crime is discovered.
