Yo soy Betty, la fea

Betty is an unattractive but a brilliant economist working as a secretary at a fictitious Colombian fashion empire, EcoModa. Betty constantly faces the scorn of EcoModa's attractive manager-owners but proves herself indispensable to EcoModa's new president, Armando Mendoza. She becomes Armando's accomplice in a clandestine scheme to save EcoModa from financial ruin and they become romantically involved. (wikipedia.org)
