Marina is the manager to a Hotel in the city. Her executive career is going through a rough patch when she is informed that her mother, Beatriz Reverte, suffers from a disease that compromises her life.
At the same time, in the town “Nuestra Señora del Mar”, lives Damian Fabre; a young captain who owns a fishing boat called “The Tempest”. Damian is in charge of supplying merchandise for a canned food manufacturer called “Neptuno”. Esthercita, the mayor’s daughter, is obsessed with Damian, and after some incisive flirting, he finally corresponds her without having a clue of what is coming close to him.
Mercedes Artigas, a mysterious and elegant woman, shows up in the city. She is “Neptuno’s” owner and she desperately needs someone who helps her save the factory from going bankrupt. She offers Marina the chance to recover her professional life by taking care of the factory’s financial and administrative management. Although she was a little skeptic at the beginning, Marina accepts to move to the town, especially when she is advised that her mother’s health would get worse in the city.
Mercedes keeps a big secret: she is Marina’s real mother, but she had to quit her daughter in the past. She used to be really poor and Ernesto, who was a mobster ever since then, fell in love with her, but Mercedes didn’t correspond to him because she was in love with Leonardo and got pregnant with his child. Furious, Ernesto killed Leonardo. Mercedes ran away and a short later she gave birth to twin sisters. Ernesto stole Magdalena, and regardless of being a girl, he abused her and condemned her to a life of prostitution. To keep Marina from having the same luck, Mercedes decided to give her in adoption.
Hernan, a wealthy and good-looking man, has always been obsessed with Marina. He has enough power to make everyone in the town surrender to him; completely different to the Hernan, Marina met in school. In order to provoke Damian’s jealousy, Marina accepts going out with Hernan, although she mistrusts him which she can’t explain why. This is because Hernan has a dark life that he shares with Fulgencio Salazar, the town’s mayor and Esthercita’s father. Hernan works with the mafia and has some problems with fishing boats, especially with Damian Fabre’s, “The Tempest”, which has complicated his business’ management.
Damian and Marina are forced to make a truce in order to defend themselves from their common enemies, who want to destroy them; this struggle makes them realize they have fallen in love and they start a romance.
Esthercita, on the other hand, is still obsessed because Damian doesn’t correspond to her love and, in her eagerness to get him, she claims in front of her father to have been raped by Damian. Fulgencio arrests him, forcing him to marry Esthercita in order to keep his daughter’s honor in front of the villagers. However, that marriage doesn’t last much and tragically Esthercita disappears when Hernan puts a bomb in the boat trying to get rid of Damian.
The day for Mercedes to rescue Magdalena has come, and she decides to stay next to her and make her the owner of an exclusive bar in the city.
Marina and Damian decide to get married but Esthercita reappears and prevents that marriage from taking place, since Damian is still married to her legally.
Marina discovers she is pregnant and suffers and accident in which she loses her baby. From then on, Marina doesn’t want to hear from Damian. Disappointed because Marina has rejected him, Damian enters “la Casa de las Muñecas” bar, where Magdalena works. Searching to be loved, she gives in to Damian who being drunk, mistakes her for Marina. Magdalena finds out that she has a twin sister and that it is because of her that Damian is depressed. However, as time goes by, Magdalena has started to love Damian, too.
Hernan convinced Marina to marry him. Damian tries to recover Marina’s love, but Hernan manages to put him against her, and decides to lock her up. Marina asks Hernan to remove the guardians in exchange for accepting him and allow her to say good bye to Damian. When he sees her arrive to “The Tempest”, Damian is surprised. Thrilled, they make love. After that, Marina asks him to forget her and go on with his life.
Marina and Hernan get married, but on their way back home they are victims of an attempt in which Hernan is seriously hurt. Marina dedicates her life to look after him affectionately but doesn’t allow their marriage to consummate. He promises to retire from the mob little by little.
Facing the love Magdalena is offering to him, Damian decides to take the chance of being with her and asks her to move together. She accepts joyfully.
Now, being in such different paths and in order to be together, Damian and Marina will have to defeat the obstacles that destiny has put in front of them, because only their love has a tempest’s strength to achieve whatever comes.
