A series of murders leads Commander Trujillo to Santa Rosa de la Sal a town close to a salt mine, where he meets Victor Zepeda - a lonely teenager who works in his father's funeral home and spends his free time making crude animated horror films - who's strange behavior seems to point at him as the culprit of the crimes.

Lu has a perfect life. Or so she pretends to have. She meets the handsome, short-tempered Argentinian, Diego, who is on a visit to Mexico, and she is confident to get him head over heels in love with her. In order to win a wager with her friends, her life will take a turn when she does the impossible to win him over, including taking a trip to Argentina to look for him.

Rachel is an intelligent, modern-day woman constantly on the move. Primarily focused on her career as a diplomatic consul for the U.S. embassy, she's literally lived her life on the move, globe-trotting from city to city. Currently working in Mexico City and set to leave for London, Rachel's world turns upside down on the eve of her own goodbye party when she gets drunk and passes out on the street. Saved by Alejandro, a handsome Mariachi singer and single father, Rachel wakes up in his apartment with no recollection of how she got there. Nor does she remember that she rejected his visa the day before, which he desperately needs for his daughter. Romance unexpectedly blossoms between the two, but either sparks or fists will fly after she finds out his secret.
