一大段画外音由法学教授皮尔曼Perelman (丹尼尔·亨德尔饰演)道出，描述了自己父亲大皮尔曼Perelman Sr.(奥特鲁·高茨饰)的日常生活，他也是一名律师。他把父亲的形象刻画成一个极其严肃的人，而且自己似乎也正是如此。诺丽塔Norita(Adriana Aizanberg饰)是皮尔曼忠心耿耿的秘书，这是唯一一个他可以坦诚相对的人。
　　儿子皮尔曼的课程出现了轻微的混乱，原因是在公众面前他个人的感情出了问题。他的学生中有一个是普拉提教练桑德拉Sandra(Julieta Diaz饰演)，教授一心想和她结婚。为了她，皮尔曼开始练习普拉提。终于有一个大好的机会降临了，桑德拉遇到了法律上的麻烦，皮尔曼帮忙打赢了这场官司，只是没有告诉桑德拉他的事情必须由父亲来决定。
　　当我们再次看到皮尔曼和桑德拉的时候，他们已经结婚了而且还有一个两岁的儿子加斯通Gaston(伊洛·布尔曼饰演)。接下来发生了一件有趣却也很尴尬的事情，他忘记了父亲65岁的生日。影片集中展现了他和父亲的关系，父亲总是旁敲侧击地给他暗示，但他依旧没有想起来。就在桑德拉教授普拉提课程的时候，皮尔曼独自在家照顾加斯通。

　　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.
