Música Para Si (1979)

A woman arrives home, apparently coming from her job, and sets out about house chores and placing every object around her with extreme care. The only company she has is the radio, tuned to a station of popular music hits that the audience can ask for by telephone. There is a single hint that she may have breast cancer. Then, she sets the table for a large dinner - for one - including a champagne bottle. She commits suicide by pills overdose, before she utters a word.
