¿Quieres ser mi… hijo?

Lu, a complacent 40-year-old woman, one day discovers that her partner of 15 years has been cheating on her. At that moment, Lu decides to return to her single apartment to start over from scratch, since she feels stuck and heartbroken. She meets her new neighbor Javier, a young, handsome womanizer who is only 23 years old and who won't let her rest with his constant parties. To land her dream job, Lu decides to lie in her interview, saying she is a family woman with a 19-year-old son. To make matters worse, she has to face the final test to be hired: spending a weekend in Valle de Bravo with the company executives and their families. Desperate, Lu offers Javier the job of pretending to be her son, and in exchange, she won't bother him anymore when he's out partying.
