Mauro arrives in Havana in order to carry out the request of delivering money to Carola Gorostiza, a member of his future family by marriage. However, he is the one who is the subject of the most unexpected business proposition one can imagine.

After his terrible decision to invest in the business of the slave ship, Mauro must deal with the moral consequences. Ultimately, he decides that he will betray Carola and collaborate with the abolitionists so that the slaves cannot be sold. For her part, Soledad will have to face her stepson, Alan from whom she must hide Edward's mental illness.

Luis's death has a profound impact on all the characters, both in Cuba and in London. Mauro and Gustavo engage in a game of billiards, on which their respective futures depend. Sol decides that she and Edward must flee from London to Jerez before Alan declares her husband legally unfit and takes the entire family fortune.

Mauro and Santos arrive in Jerez to take possession of their newly acquired possessions. This is where Mauro finally meets Sol, who - far from contesting what once were her family's assets - will ask Mauro to help her in a matter of life and death.

The arrival of Carola Gorostiza from Havana puts Mauro and Sol in a dilemma, and they are forced to detain her so that she cannot threaten them. But Carola will not be the only threat that our protagonists will have to face. The appearance of Alan Claydon will put Soledad's life in danger when he threatens her to get the inheritance money.

After saving Sol from Alan's assault, Mauro expedites the sale of La Templanza. On the other hand, to protect Edward from her son, Soledad finds a perfect hiding place for her husband: the convent where Inés lives in seclusion. But Sol does not imagine that she has placed her husband in the hands of greater risk, since the flames of an old love will be rekindled with unforeseeable consequences.

A terrible confrontation between Mauro and his son will cause a rupture that Carola Gorostiza will exploit to recover the possessions to which she believes she is entitled. On the other hand, Soledad - unable to accept the consequences of her love affair with Mauro - decides to flee Jerez taking her husband with her.

After being responsible for the death of Santos Huesos, Alan Claydon discovers Edward's whereabouts. He commits one last desperate act and - to force Edward out - sets fire to the convent where he is staying. Sol and Mauro will risk their lives to try to save him. Will they succeed... or will they pay with their lives in the attempt?
