In this knockabout Spanish comedy, Sofia (Rosa Maria Sarda) gets married, builds a successful career as a pianist and is a loving mom to her children, then one day, she wakes up and realizes she's a lesbian. Sofia's three grown daughters all react to their "new" mom very differently, but neurotic sibling Elvira (Leonor Watling) takes the prize when she hits upon a scheme to break up her mother's relationship by seducing Sofia's new lover.
