Sixty-year-old Frank Macchiano is a respected man in the Californian city of San Diego. He is a reliable business partner, a loving father, a tender lover, and even as an ex-husband, he is caring and tactful. However, in his youth, he was a fearsome hitman nicknamed Frankie the Machine. Frank parted ways with the mafia a long time ago and until recently he hoped that it would be forever. But one day he could not refuse a favor to his former boss, and this led him into a deadly trap. To save himself, Frank must quickly understand who needed to kill him and why. The problem is that the list of candidates is not much smaller than the local telephone book, and time is running out.
