Why do we cling to what harms us?
Helena is desperate, she needs money to pay off her mounting debts as she has been orphaned and must take care of her younger brother who frequently falls ill.
A position as a presidential secretary at INDUSTRIAS ALLER S.A. could change her life, but Helena never thought that an essential requirement would be having to endure the daily presence of the company's CEO, Sebastián Aller, eldest son and heir to almost all the wealth, as well as being an arrogant and narcissistic ogre.
Helena's desire for a better life will intersect with Sebastián's desires, who rejoices in the fact that his wealth will increase by entering into an arranged marriage with his new European wife, until a new clause in the contract that his lawyer forgot about appears as a stumbling block. Sebastián fears not being able to fulfill this new requirement, risking losing everything and leaving his envious and resentful younger brother Alan as the new CEO, who will stop at nothing to destroy his life.
Will Helena be the one to help Sebastián fulfill this clause? 
Helena does not know how far she will go to ensure her brother has a better life.
