She works as a prostitute in Madrid and longs for a legitimate job. Whenever she builds up her savings, her housemate and best friend Tomás finds ways to spend, lose, or cost her those funds. She meets Raúl, whom she likes and who likes her; the trouble is he also likes that part of her she wants removed.
