Dora, a 45-year-old biologist lives alone in an isolated house, where she conducts an ethically questionable research. Looking for a partner she can trust, she hires a new caretaker, Mateus, not realizing that he is also hiding his own secrets. Gradually, the two grow closer and Mateus finally discovers more about Dora's research: human composting. Mateus, who applied for the job in search of his father, who he believes to have worked at the house before disappearing without reporting, confronts Dora, but she manages to lure him like prey into her office, in the Tree House.
