Isabela's husband leaves sweet home; his younger girlfriend already pregnant with twins. Dealing along with menopause hot flushes plus sweats -always carrying a fan-, Isabela meets Emiliano, a mature mexican man who seems to know a great deal on how to give unconventional pleasures to women.
But Emiliano is a misterious lover who appears and vanishes without any explanation and the police visits Isabela enquirying about him; no one knows who is he or how he earns his living.
Meanwhile, Isabela's daughter, a concerned psychoterapist, having discovered her mum's amazing sexual life, thinks she needs to get into therapy. As Isabela refuses it -actually, she's enjoying the whole thing- daughter seeks the advice and help of her father. Surrounded by nappies and baby's bottles -twins have already landed- he hears the news with astonishment -he always thought Isabela frigid- and falls immediately in love again, wanting to come back to his former wife....
Isabela's peaceful life becomes a thrilling funny plot full of ''embroglios''.
