Eliza is beautiful, intelligent and independent, and at 29 she’s still single by choice. She wants to find happiness in her professional life and her private life. She resents this society that calls single men of her age “a good catch” while women are called “spinsters”. Thanks to her ability to express her opinions in writing, Eliza gets a job at a prestigious magazine where she writes her column “Solterita y a la orden” (Single and available). There’s only one problem: her boss is a millionaire bachelor who she knows from her past. He’s the same person who during high school was the typical shy, nerdy guy who got mocked by everybody, including her. Now Eliza has to be accountable to him, and in spite of their continuous confrontations, a great attraction grows between them. This is the story of Eliza and all the men and women that work together, have fun together and live in the neverending battle of the sexes that is very familiar to all of us.
