La vida privada de Piero Garza

San Sebastián, present day. Gala, a woman who was the victim of a "love scammer," commits suicide. The case is dismissed by the judge due to lack of evidence, but the deceased's family hires a private investigator, Fernando Astiz, to investigate the alleged scammer's new life and gather information on potential new victims, with the intention of reopening the case. The detective discovers that the scammer is living with a new, wealthy girlfriend. They live as a couple, and he seems genuinely in love. She is an attractive and wonderful young woman, but she could be just another victim. At the same time, Astiz learns that the scammer is also involved with a young man from Valencia and an older woman from Pamplona. He also discovers that the scammer wants to completely put his past life behind him to start a new one with his new partner.
