Sofia (Rosa María Sardà) is a pianist who lives in Madrid and has three adult daughters. On her birthday, she announces that she has fallen in love, but the sisters don't handle it very well when they find out that mom's new lover is a Czech woman about their age. Elvira (Leonor Watling) is particularly bothered by it, since she is unstable and her identity seems to be so tied to her mother's.

The selfish sisters go about trying to remove Eliska (Eliska Sirova) from their mother's life and decide to show mom that Eliska isn't serious or faithful to her. The plan is for Elvira to seduce her, and although Eliska doesn't fall for that, Sofia believes that she has cheated. The couple break up, and after seeing their mother so unhappy, her daughters now have to fix the big problem they created.

This is a nice film about real "family values," with a sweet romance. If you're a fan of Pedro Almodóvar, you'll also appreciate the comedic style.
