Chief inspector Paul Fein and his eldest son inspector Ben Fein investigate the double murder on banker Phillip Chandler, whose family is also in politics, and his wife. Their first suspect, heir Evan Chandler, is found murdered in his car. Paul is likely to succeed the chief of police who is about to retire, but then finds he was involved in a major drug-related corruption web, and when he chief is killed becomes the rage of various accusations; even taken off the case, Paul and Ben keep investigating, forcing a fiscal investigator to collaborate. Junior son Eddie Fein feels guilty for failing to save his partner's life, even if officially cleared, and saves Caroline Chandler's life.
