1951年，罗伯托不顾母亲反对，执着追寻电视事业的梦想。他尝试涉足喜剧领域...同时也初尝爱情滋味。

此时已改艺名为"切斯皮里托"的罗伯托，决定转战另一家电视台试运气。虽几经挫折，他最终成功创作出备受欢迎的喜剧短剧。

查帕廷博士的辞职让罗伯托的事业岌岌可危，他必须在高层将他的位置交给其他喜剧演员前创造一个新角色。最终，是他的机智和一个旧点子化解了这场危机。

1936年，年幼的罗伯托被送往瓜达拉哈拉，在那里艰难适应新环境。数十年后，已成老戏骨的"切斯皮里托"在八频道失去重要支持者后陷入迷茫，但童年记忆却激发他创作出巅峰之作——《八号房的奇遇》。

随着《八号房的奇遇》走红，罗伯托获得更多创作自由，八频道的竞争对手们争相招揽"切斯皮里托"。然而名利双收却给罗伯托及其团队、家人带来诸多困扰，使这位喜剧大师迎来创作最丰硕——却也最心力交瘁的时期。

随着罗伯托事业蒸蒸日上，《八号房的奇遇》剧组开启国际巡演。然而当丈夫全身心投入工作时，格拉谢拉却要艰难适应作为明星妻子的新生活。

As Chespirito's characters reach the height of their popularity across Latin America, Roberto relishes in his newfound level of fame -- while growing more distant from his family back home. In Acapulco, Roberto finds himself struggling with what he feels and what he thinks is right.

Roberto gets his team together for one last project -- a comedic soccer film called El Chanfle. While the cast and crew come to blows on set, Roberto faces a choice between his past and his future. Later, a warm welcome in Colombia reminds Chespirito of his true purpose: making people laugh.
