Stella is leaving the studio. She is turning on the car, when a misterious woman in balaclava and black leather gloves, hidden on the backseat, grabs her from behind and puts a chloro cloth over her mouth and nose. Stella tries to remove it, but the hitwoman keeps it tight. The substance takes effect and Stella faints.
Stella wakes up. She finds herself tied up and gagged with duct tape. Hitwoman plays with her, putting her gloved hands over her mouth and nose. Stella can't breath, because she presses them tightly. The masked woman uses her gloved hands to strangle her victim too.
Hitwoman takes a nylon bag and puts it over Stella's head. She handgags her, to be sure she can't breath under the bag. A long and intense breath torture. The woman doesn't remove the bag. This is the final action, where Stella definitively dies.
