Citadel: Diana Show Summary

Milan, 2030: Eight years ago, the independent global spy agency Citadel was destroyed by the powerful enemy syndicate, Manticore. Since then, Diana Cavalieri, an undercover Citadel agent, is alone, trapped behind enemy lines as a mole in Manticore. When she finally sees a way out and the chance to disappear forever, the only way to do so is by trusting the most unexpected ally, Edo Zani, the heir of Manticore Italy and son of the head of the Italian organization, Ettore Zani, who's vying for leadership against the other European families.
