Paloma is a young psychiatrist, who is hired to work as a director of a clinic in Galicia, and is attracted to Mario, her very first patient. He suffers from a rare form of amnesia, commonly known as Korsakov's syndrome. As a result, both his short and long term memories are affected, and he has temporary lapses of perception. However, Paloma finds Mario to be a fascinating individual, not just a regular patient. Intrigued, she decides to explore Mario's past and, through their dialogues, their relationship takes an unexpected turn.

Paloma, una joven psiquiatra enamorada de su trabajo, conoce en un hospital a Mario, un paciente inquietante y seductor que padece el síndrome de Korsakoff: una extraña enfermedad que altera la memoria y por la que Paloma está muy interesada. Empieza a tratarlo, y la relación entre ambos se hace cada vez más estrecha. Él le inspira sentimientos contradictorios, miedo y atracción simultáneamente, aunque ignora que la memoria de Mario oculta un pasado tejido de hechos perturbadores. (FILMAFFINITY)
