In 1967 Buenos Aires, eight year old Valentín lives alone with his poor widowed paternal grandmother. He has not seen his mother since he was three. His grandmother tells him that his mother was unfaithful to his father. Regardless, Valentín still misses her. His womanizing father, Vincente, is on the most part absent as a traveling salesman, he who seems more concerned about his own fortunes than sending money home to take care of his mother and son. Valentín has dreams like most young boys, his primary one being to become an astronaut. He believes the work that he does building rocket models and space suits will assist the NASA space program, and he does whatever he can, such as walk around in heavy shoes to simulate zero gravity and hold his breath underwater, in his pursuit of becoming an astronaut, despite being slightly cross-eyed and near-sighted, which he believes will not hinder his chances. But without really realizing it, he wants more than anything to be part of a nuclear family, with his father at home and for his father to marry a pretty young woman he can call his mother. He believes Vincente's latest girlfriend, Leticia, is that woman. In the absence of a constant male influence at home, Valentín searches those out, whether it being his Uncle Chiche who is visiting from Ushuaia, or Rufo, the bohemian pianist who lives next door. Valentín tries to solve what he sees as the problems in his life to varying degrees of success, and comes to some new understandings which reconciles what he has been inadvertently told in the past and what he now sees in life. who wouldn't love you, sweetie?。Valentín！。Sensible pero no frágil。 瓦伦丁（罗德里戈·诺雅 Rodrigo Noya 饰）是一个8岁的可爱男孩，他成长在一个破碎的家庭之中，和祖母（卡门·毛拉 Carmen Maura 饰）过着相依为命的生活。瓦伦丁的父亲是一个名副其实的花花公子，总是不停的更换着身边的女伴，这一次，一个名叫蕾蒂西亚（朱丽叶塔·卡迪纳利 Julieta Cardinali 饰）的女人成为了瓦伦丁父亲的新任，蕾蒂西亚非常的友善，和瓦伦丁之间的关系很要好。 后来，蕾蒂西亚和瓦伦丁的父亲分手了，但是她和瓦伦丁之间的来往却并没有断绝。蕾蒂西亚经常带着瓦伦丁去吃饭、看电影，而瓦伦丁也总喜欢将自己的所思所想向蕾蒂西亚倾诉。
