Marisa Ventura is a hard-working, intelligent and determined single mother who dreams of a better life for herself and her son, Ty. As a housekeeper at Manhattan's first-class Beresford Hotel, Marisa has made a good life for herself and her ten-year-old son, even if they don't have a lot of money. One Saturday morning Marisa brings Ty to the Beresford. She asks a co-worker to keep an eye on him for her while she and another maid, Stephanie, attend to their chores. One of the hotel guests, a spoiled socialite, Caroline Lane, asks Marisa to return some designer clothes for her. After Caroline leaves, Stephanie coaxes Marisa into trying them on before taking them back to the store. In an uncharacteristically frivolous moment, Marisa slips into the chic, expensive outfits. Ty appears at the door with the handsome Christopher Marshall, an aspiring U.S. Senator and one of Manhattan's most eligible bachelors. Ty has come to ask Marisa's permission to walk through Central Park with Christopher and his dog Rufus. Christopher is immediately attracted to Marisa. Assuming she is a hotel guest, he asks her to join them. She is about to refuse, but Stephanie intervenes and accepts for her. Despite the obvious sparks between them, Marisa is reluctant to encourage Christopher, fearing she'll lose all that she's worked so hard to build. But he pursues her, even though it could compromise his political career. As romance, mistaken identity and front-page gossip collide, Marisa and Christopher learn that the bigger your dreams, the better the chance they might come true.
