Five years have passed. Yu Fengcheng and Bai Xinyu, once comrades guarding the frontier, reunite at a crossroads in their lives. One is an emergency rescue team captain, carrying the scars of PTSD and continuing his mission in the northwestern Gobi. The other has outgrown his youthful inexperience and become a successful entrepreneur in Beijing's business world. Their reunion at a glittering reception brings five years of estrangement to the surface. An old scar on a wrist stirs memories of their military days, while a sudden geological disaster in the northwest puts them side by side once more amid the ruins. From a tangle of misunderstandings to standing together through life and death, can the honesty they share at the hospital bed untie the knots of the past? As the rescue captain's iron will collides with the entrepreneur's tenderness, how will they weather the challenges of a long-distance relationship and difficult career choices, and bring the spirit of the white poplar back to life in their everyday world? This is a continuation of growth, redemption, and love, witnessing two young white poplars put down intertwined roots and sprout fresh green leaves anew through the trials of time.
