The return trip of a female doctor who studied abroad was disrupted by a gang hunt. On the Linjiang Port passenger ship, Su Wanqing had just woken up from her dream in the autopsy room when she bumped into Xie Chengzhi, who was wounded and fleeing - he held the muzzle of his gun against her temple with gunshot wounds, but when she calmly confronted her and said, "You can't get off the boat with your injuries," he let down his guard. In the small cabin, she held the knife to retrieve the bullet and sutured the wound, while he bit the pillow to resist the pain. The smell of blood and tobacco mixed with the mist and rain outside the window, creating a different kind of ambiguity. The threat of the Blackstone Gang has not disappeared, and she hides the old hatred of her father's injury. He carries the mystery of his unknown identity. This encounter that started as a "healing" is destined to involve the two in a whirlpool more turbulent than the river.
