Rose (2020)

The story of a young couple living alone in the woods, who must contend with a life-altering illness that manifests itself in a violent and terrifying way. Rose’s disease is a vampiric, parasitic thirst for blood. As her hunger grows, all humanity seems to give way to a feral violence that harms both her and those around her. Their loving relationship strains under the burden of Rose’s illness, and it is only a matter of time until the secluded life that they have built is upended entirely.
