When VERA (Lola Dueñas) was young, she couldn’t take care of her newborn child. When CORA (Ana Torrent) was young, she was told that she could not have children and that the only way to start a family was to adopt a child.
This is a film noir story about a crime. A meeting of these two women on the banks of the Duero River.
Javi, an unfaithful, powerful man, drives down a poorly lit infrequently traveled road by night. He’s returning home from a supposed work trip. In the blink of an eye, one mistake will change Javi’s live forever.
Luz, a candid and responsible young woman, is hired as an intern. His only job is to take care of the lady of the house: an old woman in a vegetative state, unable to speak, move or do anything for herself.
It is a hard, routine and suffocating task. Little by little, Luz begins to take its toll. So much so that, as the weeks go by, he begins to develop an unhealthy obsession with the old lady...
...until turning work into a disturbing game of dependency and submission.
