Charlotte cooks Giada’s favorite dish in their one-room Rome apartment, reflecting on her perpetual hunger that she hides from Giada and on the tenderness of their six-year life together. As Giada returns home, cheerful and talking with someone, Charlotte opens the door expecting a joyful reunion only to see Sabine on Giada’s arm. The shock unmoors Charlotte; Sabine is dazzling and predatory, and Giada, unaware of the danger, begins to invite Sabine in.

Charlotte sharply forbids it, and Giada realizes something is wrong. Sabine seizes Giada, holding her at the threshold while Charlotte remains inside, protected by the boundary of her claimed home. Sabine taunts them both, asserting that if Charlotte truly loved Giada she would step out or have turned her. Charlotte, knowing Sabine’s ruthlessness and the trap at the door, refuses to move.

As Sabine presses her advantage, she exposes Giada’s throat and asks whether begging will make Charlotte cross the threshold. When Giada begins to plead, Sabine snaps her neck; the crack echoes in the stairwell. Charlotte stifles a scream, consumed by rage and grief, but she cannot attack Sabine because of an old promise that binds her hands against her maker. Sabine calls Charlotte her creation and claims it is her duty to prune any “weeds,” confirming she sought Charlotte out and eliminated Giada as a distraction.

Stopped at the threshold by Charlotte’s warding, Sabine lingers, inviting entry and briefly flickering with the semblance of the lover Charlotte once knew. Charlotte refuses, asserting Sabine is not welcome. Sabine remarks that something is burning and withdraws, leaving Giada’s body in the hall.

Charlotte rushes to the kitchen to find the dinner ruined, then returns to find Sabine gone but Giada’s corpse still there. She steps into the hall, lifts Giada tenderly, and carries her to their bed. Overwhelmed by grief, Charlotte sobs bloody tears and screams into the pillow until she is emptied of breath and strength.

Knowing nothing can be saved, Charlotte whispers an apology to Giada, leaves the front door open so someone will discover the body, and runs, abandoning the home and the life they built together.
