Giovanni Napolitano

In Naples at the end of the 19th century, Nicola Bellizzi dreams of becoming a lawyer. However, when he seeks the reason that people are reluctant to help him in his goals, he discovers that some of his blood relations are high-ranking members of the Mafia. He tries to break away from his family obligations, but falls into a life of crime and violence.

A Mafia boss fakes his own death aiming at a fresh start, but a nurse happens to see him alive and well after the funeral. A hitman is promptly sent to get rid of her, only to find out she's his first and unforgotten love.

After his handler is killed, police dog Rex teams up with recently-divorced inspector Richard Moser to investigate crimes and solve mysteries on the streets of Vienna. And they sometimes get help from their two-legged friend, Inspector Stockinger.
