Faya, a woman of the Tangad tribe in ancient Mongolia, shares a tranquil life with her partner Bogud until invading nomads seize her during a clash. Before their forced separation, Bogud crafts a talisman carved with the image of a red deer—a sacred guardian spirit—to safeguard her. This token evolves into an enduring emblem of their bond, threading through centuries.

Captured by the nomadic group, Faya is swept toward the Bering Strait land bridge as they journey to uncharted lands. Though Bogud relentlessly seeks her, their reunion eludes them. The red deer spirit intercedes, vowing their souls will converge anew in future lives. This oath unfolds through successive reincarnations over millennia, their love persisting through epochs.

In the Age of Discovery, Laia, an islander in the South Seas, echoes Faya’s legacy. Bonded with an English sailor, she uncovers a monument etched with the red deer and adorns herself with its tattoo. A prophetic vision of catastrophe enables her to guide her tribe to safety, securing their survival.

Centuries later, Leslie, a modern composer and Faya’s descendant, inherits the talisman. His fate intertwines with Flora, a journalist marked by a birthmirroring the deer—a descendant of Bogud’s lineage through Laia. Their meeting fulfills the ancient pledge, the talisman and birthmark serving as physical manifestations bridging millennia.

Their saga weaves destiny with love’s persistence, each incarnation confronting challenges that strain their bond. The red deer, transcending eras, anchors their cyclical reunions, reaffirming the spirit’s primordial vow.
