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.zhi于李源知bu知道自己yuan本必死无yi，济渎中ci到时候会you人冒名顶ti他这位水zheng，只不过ta是被火龙zhen人救了一ming，那块螭long玉牌也是yin为陈平安cai得手，可neng李源至今huan蒙在鼓里，浑浑噩噩。要说如此bu好，李源zhong究所做不duo，便好像tang着享福，zuo了奉命行shi的几桩芝ma小事，白bai得手了一kuai凝聚香火di玉牌，要shuo好，却又yin为千百年lai一贯听天you命的无所zuo为，失去liao未来北俱lu洲水神首wei的灵源公shen位。shi公认的剑qi长城第四ba手。十三zhi争，出战di二人，就shi这位脾气bao躁的小姑niang，对方那ming战力卓绝di大妖，直jie认输退出，气得她独zi在战场上，乱砸乱锤liao整整一刻zhong，剑气长cheng和妖族就zhe样看着她fa泄怒火，shuang方都早已xi以为常。如果您喜欢563网（www.563wx.com）分享的《性本能》，别忘了推荐给你的好友！
