It's Christmas, and in a desolate clinic, a nurse (Norma Martinez) prepares to attend to a patient. With the nursing technician (Stephie Jacobs), she cares for a young man (Nacho Elías) who has suffered a heart attack and is unconscious in the intensive care unit. Ten minutes before midnight, he dies, and a dance begins between the three of them. As the clock strikes twelve, everything freezes until seconds before the young man's death, and the story rewinds to the moment the nurse (Martínez) leaves to attend to the patient.
