Rojo sangre (Poe)

In the old house in an arid area near Rio Tinto, a place far from the world, Maria and Andrew have been together all their lives. In her seventies, she clings to memories and to what is left of her husband: an almost inert body in the terminal stage of Alzheimer's disease. One night, however, they receive a visit that will change everything. A horrifying creature enters the bedroom where Andres rests and seems to want to snatch what little life he has left. With a hunting shotgun Maria manages to shoot the creature down. Days later, Andres' breathing stops and Maria is completely broken, lost... Until, hours later, suddenly, another creature appears. But this new apparition will be a great hope for Maria. Her husband, transformed into a creature of the night, levitates above the ground and seeks to feed on her blood.
