Since humanity's first steps in the Stone Age, Methuselah has harbored an ancient secret. Cursed by the shaman to witness the end of days, he searches in vain for a home, place to place, clan to clan, yearning to belong. First in prehistoric Africa and lately disillusioned with love for a hundred years in the New World, he learns all too well to guard his heart and hide his story. That changes when a car crash lands him in the hospital with a fractured skull. Doctors discover strange stem cells in his blood, promising cures and a fountain of youth. Methuselah faces choices of life and death. Forced on the run again, he comforts himself by reliving a happier time, when he and Arrow, his first love, raft across the paleo-lake Makgadikgadi, which rested in those days on the vast Kalahari. In their age-old journey, the cavemen lovers find a place to call home and learn what it means to belong. While Arrow's enlightened sensibilities get the two of them in trouble and challenge Methuselah's judgment, their adventures in an untamed world bring them together. When Methuselah's enduring youth reveals itself through the passing seasons, he and Arrow bravely face a dire reality. From the distant past that lives inside Methuselah, Arrow's spirit reaches out, providing guidance for our threatened times. He gives Methuselah the strength to do the right thing and the courage to live his true self in the modern world. Arrow's memory opens Methuselah's heart and renews for him a hope of redemption in the arms of a caring man today. If only Methuselah permits himself to love once more.
