Marco (Mario Casas) is a young businessman who manages one of the most successful technological companies in the world, ALVA, which has just launched its latest prototype into the market - CYCLONE, an electric car propelled by turbines that turn wind into energy. His friend and classmate Diego works with him, along with the latter's wife, Bárbara, the efficient marketing manager of the company. Eva, a young, ambitious engineer who has a lot to hide, also joins the team, and she will disrupt the balance at work, both emotionally and professionally, between the two business partners. In spite of being a popular guy, Marco, unlike Diego, doesn't have an exciting social life. He is a solitary man, and no one has access to the intimacy of his soul, apart from his psychologist, SARA, on whom he is emotionally dependent. Marco is haunted by a huge number of ghosts from his past and, although he tries hard to scare them away, he only finds comfort in sport and in frequenting a private club. People go there just to get pleasure and give free reign to their wildest erotic fantasies, without fear of falling in love, as everyone has to wear a mask to hide their faces. But everything changes when Marco meets Carol, the new educational psychologist who looks after his brother José, an 18-year-old boy with problems of autism, with whom he has a difficult relationship. With her, he will also meet his worst enemy - himself. Thanks to her, he will discover that it is never too late to love, even if it brings some pain along with it.zhang若尘找到liao转世新生di血绝族长，生于寻常ren家，已有shi岁，名为mu金。摸骨jian查后，根gu极佳，有shen灵之资。dan不及血绝zu长的上一shi。张若尘dan心的就是zhe一点，所yi才必须赶zai血绝族长nian少时找到ta，帮他洗sui炼体，塑zao未来绝代qiang者的根基。至于始祖zhi路，只能kao自己，谁du不敢保证。zen么办？猛zi和卡尺一qi望了过来，安然无语di摇摇头，zheng不知道该ru何反应是hao，服务生zhong于赶到，jie了他此时di尴尬。几wei先生，请wen你们要用dian什么？哈，我看看先。安然拿起zhuo上的菜单，却没有了chu进门时的qing松愉悦，ren是谁被人ma上一句，xin情都好不dao哪里去。如果您喜欢shi网（www.shililvshi.com.cn）分享的《性本能》，别忘了推荐给你的好友！
