Primer Amor... a mil por hora tells the story of a fourteen-year old girl named Giovanna Luna (Anahí) and the obstacles she has to overcome to find happiness with the love of her life León Baldomero (Kuno Becker),
in a world where teenagers try to live their lives too fast without
considering the consequences. The obstacles for the couple are not few;
in the first place we have Catalina, Giovana's mother, who insists that
her daughter have a fifteenth-anniversary party, which will cost well
over the financial possibilities of the family. She also totally
disapproves of her daughter's relationship with León Baldomero, who she
considers has no money or future.
On the other hand, we have the malicious Demián Ventura (Mauricio Islas),
junior who is infatuated with the beautiful adolescent,Giovana . He
desires to have her at any cost, without caring who he will hurt in the
process. And of course there is Priscila, the jealous older sister of
Giovana, who feels out of place in the family. She releases all of her
bitterness on Giovana, and even promises to get rid of León Baldomero,
for better or worse.
Accompanying Giovana in her path, which is not always an easy one, is her best friend, Marina Iturriaga (Ana Layevska),
a high-class fourteen-year old girl. She is the daughter of the famous
actress Pilar Camargo, who is always busy and gives expensive gifts in
place of affection. Marina's father, Antonio Iturriaga, is the same
way. He is a shady businessman and in his hypocritical actions he will
shame his daughter, that will end up causing her an eating disorder,
which will put her life in danger.
However, Marina's dream of love is given hope, incarnated in Imanol (Valentino Lanús),
an educated and handsome young man that has returned to Mexico after
having finished his studies in the United States. The only problem is
that Marina, because of a her pride refuses to open up to Imanol, she
doesn’t want him to question her actions so she can’t overcome her
pride and refuses to look for comfort from everyone except Giovana
Luna, our protagonist. This will cause tension between the girls in the
moment that they most need each other, forcing them to prove their
friendship to one another.
