At 99 years old, Frank Lucianna is the oldest practicing attorney in America. And now, he's preparing to mount his final criminal defense. Frank has lost a step, but he won't be alone: his law partner is Frank Carbonetti, the son he never had. Together, they hope the case will be the old man's greatest.

But as the trial approaches, Frank starts to ponder what it all means. He’s defended more than 100 murder cases in his career. As a devout Catholic, he believes in redemption. And yet these monstrous crimes haunt him. Young Frank soon learns why his old man never retired: because when we love people, we keep showing up for them.
