A wealthy sophisticated woman (Rosaura) abandons a newborn baby girl in a boarding school, and leaves nineteen diamonds with her. 18 of the diamonds are meant to pay for each year of her school expenses, until the baby reaches eighteen years old, and the last diamond is pink colored, and is supposed to be given to the baby girl when she grows up and is ready to leave the school. Years pass, Rosa turns into a beautiful young lady. Her biggest treasures are her boundless imagination and her friendship with Eva, who is another girl at the boarding school.

One fine day, Eva meets a boy named José Ignacio, a wealthy young man who makes fun of her and pretends his name is Adam, just to lure her in. The young Eva falls in love and ends up pregnant but Jose Ignacio leaves her. After giving birth, a terrible car accident abruptly ends Eva's life. Rosa, who was also in the accident, is mistakenly identified as Eva in the aftermath, and Rosa lets everyone believe she really is Eva so that little Eduardito will not end up in an orphanage. Rosa sets on a plan of revenge on Jose Ignacio, who just happens to be Eva's cousin, Barbara's fiancé. She also strives to give Eduardito proper love.
