Ignacia (
Ana Layevska) is a young engineer working at a large
construction company, Omega Construction, which is owned by Tomás Villamayor (
Fabián Ríos), her boyfriend. They spend much time together and finally decide to get married, but Ignacia misconceives the kind of person that Tomás really is. Shortly before their
wedding, they have a very strong fight in which Tomas tries to hit her but is foiled by the intervention of Pedro. that makes Ignacia leave the town and take time for reflection. She meets Pedro o Pérez (
Jose Luis Resendez), a simple
laborer without money and big aspirations, who makes her forget all her problems. The attraction between the two is immediate and mutual (love at first sight). They cannot avoid spending a memorable weekend together, which ends on a Sunday afternoon by when the two are madly in love with each other. However, Ignacia knows that, what she is experiencing is a dream, a parenthesis in her life. When Pedro awakes on Monday morning, he thus finds a note at his side saying that Ignacia thanks him, and she is leaving without a trace. On Ignacia's return home, Tomás is awaiting her with the news that he is offering her a new position in his company and he is looking for her forgiveness. She agrees but gets surprised when she comes to the workplace in her position of construction supervisor to see Pedro as a worker at the construction site. Despite having every reason in the world not to be together, Ignacia and Pedro discover that their love persists over all prejudices, differences, rejection and, the many, sometimes cruel, obstacles raised by others, who want to see them apart. == Cast ==
