Madrid, Spain, early thirties. The charming playboy Sergio Hernán is an unscrupulous womanizer who over the years has seduced and abandoned hundreds of women with the complicity of Oshidori, his cynical butler. However, his brief encounter with Elena Fortún, blonde, posh and a bit cheesy, unexpectedly leaves an indelible mark on his soul.
