里约热内卢的中央车站，朵拉（费尔南达-蒙特内格罗Fernanda Montenegro饰）在这里帮人写信。但她会把看不顺眼的信统统撕掉不寄，甚至公开读信里的内容取乐。朵拉生活拮据，年纪不小却还未嫁，或许在她内心，人与人之间的真情根本就不值得信赖。
小男孩约书亚（文尼西斯•狄•奥利维拉Vinícius de Oliveira 饰）的出现令她开始了一段重新认识人生的旅程——约书亚很想见到远方素未谋面的父亲，不断写信给他。男孩母亲意外的车祸让朵拉决定陪伴约书亚前往东北部寻找父亲。在约书亚眼中，即使父亲很陌生，却总是骄傲地谈起父亲。而朵拉，也同样有着一段和父亲的痛苦往事。在约书亚寻父的过程中，朵拉因为往事而冰冻的内心慢慢回暖。

源自William Blake的诗The Tyger，是一部很前卫的实验动画。片中融合各种元素，木偶，板画效果和现代的数字技术。影片在制作过程中最大的挑战来自于图象，如何使最后的图象中各种元素看起来一致。少有的视觉效果，值得欣赏。
As the lights of a carnival midway dim, a huge tiger emerges from the dark. As it walks through the city, illuminated plants flourish in its path. It approaches a large apartment building: a napping man's TV goes off, he wakes and walks to the window, sees the tiger and is transformed into a monkey. Similar transformations occur as the tiger walks through the city: cars become snails, football fans become insects, hipsters outside a club become toucans. The tiger reaches a hilltop outside the city. Behind him in the city, plants glow and the air is full of flying creatures.
