小说家丹尼尔（奥斯卡·马丁内兹 Oscar Martínez 饰）从刚出道起事业就顺风顺水，如今更是获得了诺贝尔文学奖的殊荣，攀登上了职业的顶峰，然而这荣誉却并未带给他满足，恰恰相反，丹尼尔担心名声和财富会夺走他文学创作上的灵感与锋芒。
　　一晃眼五年过去，丹尼尔热度不减，邀约和奖项不断，可冷淡而又避世的他只教助手一一回绝。一封来自小镇萨拉斯的信吸引了丹尼尔的注意，萨拉斯是他阔别已久的故乡，如今邀请他踏上故土，接受“杰出公民”的奖项，在未告知媒体和朋友们的情况下，丹尼尔独自踏上了返乡的旅途，在那里，他再度见到了曾经的恋人艾琳（安德丽娅·弗里杰里奥 Andrea Frigerio 饰），如今的艾琳早已经嫁为人妻，而她的丈夫正是丹尼尔的旧友安东尼奥（达迪·布列瓦 Dady Brieva 饰）。

　　A dramedy that tells, with irony and humor, the adventures of Eliseo, the janitor of an upper class building, who, behind the back of the managing company that employs him, uses his position to surveil and be intimately acquainted with the building's tenants.
　　The building is a universe whose ecosystem has specific dynamics and rules, and Eliseo knows them all by heart. There he lives, works and absorbs every detail of the life of its residents. However, underneath all his humility, he hides a talent for manipulating them. A facade of servility and sincerity is his most effective weapon he uses on them. His power is knowledge. He knows everything about his neighbors: their names, schedules, jobs, relationships, weaknesses, likes, etc. His mind registers everything that goes on in the complex. With this advantage over his "victims", he devises strategies to influence each tenant and can calculate precisely how they will react. This game of power over the neighbors is akin to playing cat and mouse. Depending on his whims, his mood or his need to protect his position at all costs, he is capable of causing wide ranging damage. He also dispenses justice and protects those he sees as weak. He is a God on his own turf.
