La Pícara Soñadora (The Mischievous Dreamer)

Lupita is young and pretty and studies law. Although her future seems bright, for the moment she is penniless and that's why she lives in the Sares Rochild department store, where she works by day as a salesgirl in the toy department and her uncle works by night as the security guard.
Everything she "borrows" from the store to live on, she writes down in a little book so that she can repay it when she finishes her studies. She has it all planned. But one day, she meets a guy outside the office of the owner of the department store. She thinks he is there to apply for a job, and Alfredo decides to play along.
Although the owner is his father, he uses the name of his best friend, pretends to be poor and arranges for himself to get a job there in order to chase that cute Lupita. Alfredo has always been a lazy bum and a flirt, and to him, this is all a game. But soon the game turns serious when he realizes that he's falling in love with her and the secrets they both keep are standing in the way.
