In the early 20th century, life in a rural Chinese dye mill unfolds around complex loyalties and forbidden desire. Tianqing, Baotian Li, returns from a silk-selling trip to work for his adoptive uncle, Jinshan, Wei Li, a notorious and brutal factory owner. A fired worker warns Tianqing that Jinshan has recently taken a new wife after beating his two previous spouses to death for failing to bear him a son; the cruel irony is that Jinshan is impotent. Upon meeting Jinshan’s new wife, Ju Dou, Ju Dou Gong Li, Tianqing finds himself strangely drawn to her, and a dangerous tension takes root in the otherwise quiet world of the dye works.
Tianqing’s growing fascination deepens as he becomes part observer and reluctant catalyst in Ju Dou’s suffering. Jinshan subjects Ju Dou to night-time torments, and Tianqing quietly discovers the couple’s private space and the hidden bruises that mark Ju Dou. Ju Dou, who senses Tianqing’s gaze, shifts his view from objectification to humanity, and what begins as a wary curiosity gradually deepens into something more intimate and consuming. Their bond intensifies until passion overtakes prudence, and Ju Dou becomes pregnant with Tianqing’s child. To protect themselves from a society that would scorn their relationship, they deceive Jinshan by presenting the pregnancy as his own. The shock of Jinshan’s stroke, which leaves him paralyzed, abruptly compounds the crisis, forcing them to navigate a fragile balance of power and secrecy.
When Ju Dou confesses the truth, Jinshan’s response is ferocious. He attempts to kill the unborn child and set the house aflame, but Tianqing intervenes, restraining him by suspending him in a barrel so he becomes a powerless witness to the couple’s defiance. In a desperate bid to end the scandal, Ju Dou seeks an abortion at a temple nunnery. Yet the power Jinshan holds over the household extends beyond the couple: he continues to exert influence over the child, Tianbai, who is the son he named, and who grows up under the shadow of his “Father.” The tension of control and vengeance culminates in a tragic turn when Jinshan, in a moment of perilous pride, falls into a dye vat and dies, while Tianbai—now an angry teenager—looks on with a cold, unresolved gaze.
Seven years pass, and Ju Dou and Tianqing run the dye mill as Tianbai, now a volatile young man portrayed by a new presence on the scene, grows increasingly antagonistic toward rumors of his parents’ infidelity. A pivotal confrontation escalates when Tianbai confronts a local gossip, and Ju Dou finally reveals the truth about his lineage. The revelation drives a rift between the adults, and their last encounter unfolds in a dangerously cramped cellar with limited air. Exhausted and overwhelmed, Ju Dou and Tianqing fall asleep or drift toward unconsciousness as Tianbai confronts them. He drags them out into the room, and in a climactic and brutal act, drowns Tianqing. Ju Dou responds with a final, fatal act of her own: she sets fire to the mill, sealing a passion and a conflict that have consumed three generations.
This film crafts a stark, somber portrait of desire, power, and fate, where private yearnings collide with public expectations and each act of resistance exacts a heavy price. The relationship at the center—between Tianqing, Ju Dou, and Jinshan—unfolds within a harsh social landscape that values lineage and control over individual happiness, leading to consequences that ripple through the lives of Tianbai and the others connected to the dye mill.
