Set in the desolate interior of the Atacama Desert in 1934, and filmed on location in the Humberstone and Santa Laura Saltpeter Works, it classifies both as a historical romance and a working-class melodrama dealing with tyranny, classism and misogyny as principal motives, but given the wide array of characters there are substories centering in themes such as innocence, religious hypocrisy, unrequited love, narcissism, betrayal and prostitution.

The year is 1934. Deep in the Atacama Desert lies Pampa Ilusión, a company town dedicated to the extraction of saltpeter, a commodity that underwent a massive boom in previous decades, but which has sharply declined in price due to the global economic downturn and the recent invention of synthetic alternatives. This has left Pampa Ilusión struggling to remain afloat as one of the few saltpeter works still in operation.

The owner of this office is Mr. William Clark (Héctor Noguera), an English-born, despotic and bed-ridden businessman who refuses to accept the end of his economic prosperity. The daily life and routine in the saltpeter mine is interrupted by the arrival of his daughter Inés (Claudia di Girolamo), a doctor, banished from the family along with her mother when she was a newborn. She will come to discover the reasons for the exile and humiliation suffered by her mother thirty years before. Alerted of Inés's arrival, Mr. Clark orders the arrest of any unknown women found within the office, which forces Inés to lead a double life: by day she disguises as a man, "Dr. Florencio Aguirre", under which identity she becomes Mr. Clark's personal physician and eventual confidant; and by night she covertly re-takes her true personality as Inés Clark.

Under the shadow of William lives Manuel (Francisco Melo), his son (and, unknowingly, younger brother of Inés), a weak and insecure man that spends his days trying to win the approval of his mentally abusive father and hide from him the near bankruptcy of the business.

Then there is José Miguel Inostroza (Francisco Reyes), Clark's security chief and right-hand man, an exemplary employee who follows Mr. Clark's orders blindly, even if the orders are harmful and abusive to the workers of Pampa Ilusion. His obedience is affected by the arrival of Inés, for whom he falls in love, Forcing him to choose between his loyalty and his principles.

Both as "Dr. Aguirre" and herself, Inés gets involved in the daily lives of the workers and management of the mine in the midst of the revolution against her father's oppressive rule, and slowly wins over the loyalty and friendship of the inhabitants both poor and wealthy. Among these are Clara Montes (Blanca Lewin), A wealthy socialité and feminist and Inés's primary confidant, and Alberto Quispe (Juan Falcón), Clara's secret lover and a Peruvian miner fighting discrimination against his own.
