The solitude of her apartment is exactly what she needs. - until the doorbell rings and her boyfriend Marcos arrives, with both immediate and future plans that may not be exactly what Pilar needs at the moment. All she wants is to be alone. But that’s not going to happen, because the doorbell rings again, and now it’s Ema, her sister, who comes to tell her about the bad moment she’s going through with her husband. As that doorbell keeps ringing once again, the peace of this Saturday will be completely over with situations that will change more than one destiny.
