Set in the 1930s, an elderly linguistics professor named Dominic Matei, who is disillusioned and weary of life, attempts to take control of his fate by ending his life. As he walks in the rain toward his planned demise, he is struck by a bolt of lightning. Miraculously surviving, Dominic finds that his physical appearance has reversed, making him decades younger. More astonishingly, his intellectual capabilities have expanded, allowing him to pursue his lifelong quest to understand the origins of language. After his transformation, Dominic becomes a target for the Nazis who seek to exploit his newfound abilities for their own purposes. With his physical rejuvenation and mental acuity, he must navigate the treacherous waters of political intrigue and ethical dilemmas while evading capture.

Amidst the turbulence of fleeing from those who seek to control him, Dominic meets Veronica, a woman who bears an uncanny resemblance to his lost love, Laura. She too suffers a traumatic event that profoundly alters her consciousness, enabling her to remember past lives and ancient languages. Together, Dominic and Veronica embark on a journey across time and memory, exploring the depths of human potential and the mysteries of life and death. As Dominic delves deeper into his research and the unexpected consequences of his rejuvenation, he faces difficult choices that will irrevocably affect not only his destiny but potentially the fate of humanity.
