Luna caliente (English: Hot Moon) is a 2009 Spanish film written and directed by Vicente Aranda, starring Eduard Fernández and Thaïs Blume.

In the autumn of 1970, Juan, a Spanish poet living in Paris working for UNESCO, returns on vacation to his hometown, Burgos.

During his first night in Burgos, Juan has dinner with Dr. Miniente, an old colleague and family friend who lives in the outskirts of the city with his wife Antonia and their only daughter Ramona.

Juan, who believes he has killed the girl, is frightened out of the house and tries to leave when he is surprised by his host, who knows nothing about what happened, and drunk as he wants to go with him to a nearby brothel.

Juan is unable to resist Dr. Miniente's insistence once he is inside the car and reluctantly agrees to give him a ride to a brothel.

At the same time, Juan's sister, involved in the struggle against Franco, has managed to obtain secret images of the Burgos process, and seeks to hide and get out of Spain.
