Infieles

Paula is about to celebrate her first wedding anniversary. A professional offer from the magazine she works for puts her in the awkward position of having to decide about her own life, but a routine medical check-up is a warning that she has not got much time to make up her mind. Lidia meets up with Toni in a bar. They both enjoy a night of passionate love, but Lidia doesn't want any ties...

Lidia is still suffering after losing Lluis, her husband. What's more, the tribute that the co-workers want to organize for him forces her to think about him all the time. Writing the speech for the end of the event drives her to a profound crisis. Paula finally tells her husband about her diagnosis.

Marina- Joana's daughter- overhears a suspicious conversation by her father and tells Arlet about it, who prefers not to tell the secret. For her part, Arlet day by day becomes a bit closer as a friend to Dani, in whom she finds a perfect balance... quite the opposite from her boyfriend, who she feels very fond of, but she can't bear him invading her space. Cruz focuses efficiently on her job...

Once they all know about Paula's illness, all the friends, except Lidia, insist that she fight and get it operated. Paula instead chooses to show them her new home, where she always rendezvoused with her lover. What was meant to be a dinner among friends turns into a debate about whether or not surgery is the best option... Paula's husband follows her to where she lives...

Arlet can't understand how her mother still looks after her husband after all the pain he caused her. Joana is convinced that Francesc is cheating on her. Cruz and Lidia want to help her to sort things out. Paula keeps on calling Marc, her lover, but he won't pick up the phone. The girl suffers her first hallucination and starts to hear voices.

Paula tells Marc, her lover, who feels happy for having found her true love. The groups of friends are introduced to Marc, who convinces them that he is very much in love with Paula. Joana is crushed because of what about with Francesc but she is able to keep her composure in the presence of her friends. The woman recognises Cecilia, but decides not to say anything to her.
