A woman doctor returns from studying abroad, only for a gang's hunt to throw her journey into chaos. Aboard a passenger ship in Linjiang Harbor, Su Wanqing has just jolted awake from a dream of the dissection room when she runs into Xie Chengzhi, who is wounded and on the run. He is covered in gunshot and knife wounds, and presses his gun to her temple. But when she calmly tells him, “You won't make it to shore with that wound,” his guard drops. In the cramped cabin, she cuts out the bullet and stitches his wound while he bites down on a pillow and endures the pain. The smell of blood mingles with tobacco as misty rain falls outside the window, giving the scene an unexpected air of intimacy. The Blackstone Gang's threat still looms. She harbors an old grudge over her father's injury, while he carries a mysterious identity. Their encounter, which begins with “treating a wound,” is destined to pull them into a maelstrom more turbulent than the river itself.
