She is not a guest. She belongs to them

Nola and Erza are sisters hiding a dark and disturbing obsession beneath their quiet lives. Driven by control and dominance, they abduct an innocent young woman named Lana and force her to live under their strict rules. Confined inside the house, Lana is stripped of freedom and treated as an object rather than a person. Moments of release are granted only when she is ordered to perform certain tasks, before being restrained once again.
