Police detective Davide Licata survives badly wounded, so much so that his personal and love life will be affected.

Licata is tempted by the General directing the Government's "nucleous of operations and investigations (NOI)", a secret service built to do the dirty anti-crime jobs that the police can't do.

The hideout of Tani Cariddi in deep Africa becomes known - and again, the retired detective and the retired criminal must come to grips with violent action in Europe.

Not one but several traps are set from both sides of the law.

The detective exposes and destroys the man who secretively had taken the place of the octopus's head - but the crime will not stop, because the criminal's son escapes with enough power to restart it all.
