Elsa, Julia and Amelia are three longlife friends whose share two things: the same age of 50 year old, and a weekly morning walk in a city park each Thursday where they tale to the others their different daily lives: Elsa is a free-spirited maneater woman unable to have a serious relation who works as CEO in a Spanish movie distributor and who is convinced that her boss wants to have an affair with her despite he's a married man; Julia is a bitter-heart married woman who not only despises her 15-years husband, but her young students by their bad manners in her work as high-school's math teacher; and Amelia is a naive and ingenuous woman who works as horticulturist in her own nursery garden, having complications in her recent relation with Ricardo after his teen daughter, rejecting her as stepmother by not accepting the divorce of her parents. According a new Thursday morning arrives, their conversations go revealing further events: Elsa has troubles with her boss for rejecting her sexual innuendos during a travel to China; Julia is on depression after one of their student girls committed suicide jumping from a balcony, besides accusing Elsa of not accepting that men no longer see her as desirable woman for having sex; and Amelia not only has troubles after she slapped her stepdaughter in a rude discussion, but meets by chance with her previous boyfriend Alberto to discover him as a married man and father of twin babies, and with her friend Mara to learn disclose the reason to ignore her continued cell phones. With their friendship testing, Elsa, Julia and Amelia face the abyss of their own maturity, the lost youth, the broken dreams, the absence of love, the fear to loneliness and a world where a 50 year old woman turns in invisible.
