Pablo is very close to his transgender sister Tina, a struggling actress. Tina has recently been abandoned by her lesbian lover, a model, who left her in charge of her ten-year-old daughter Ada. Frustrated in her relationship with men, Tina dedicates her time to Ada, being a loving surrogate mother. The precocious Ada does not miss her cold mother. She is happier living with Tina and spending time with Pablo, on whom she has a childish crush. Tina, Ada and Pablo form an unusual family knit. Pablo looks after them both. For his next project, Pablo writes an adaptation of Cocteau's monologue-play "The Human Voice", to be performed by his sister.
