Art conservator Flora Garibaldi is just getting the hang of her new job restoring paintings in Rome, Italy. Then, her policeman boyfriend, Vittorio Bernini, asks her to join a risky search under Rome for a lost trove of Nazi-looted art worth millions. Along with an international team of art experts, they face the daunting task of locating art in miles of underground tunnels.
After they discover evidence of recent digging underground, one of Vittorio’s carabinieri colleagues is murdered. Flora and Vittorio find themselves up against a group of ruthless art thieves who will do anything to prevent the discovery of the art and its return to its rightful Jewish owners.
