在中国辽宁省大连市郊区的一个自然公园里，68岁的于大爷每天都在照顾一群梅花鹿。他如此细心地喂养和保护它们，使这些动物的数量在几十年前濒临灭绝，现在却成倍地增长。在这部纪录片中，我们可以仔细观察他的日常生活，思考他对这些动物的热情和爱是如何成为他唯一的目标，甚至可能是他的痴迷。

Uncle Yu, a lonely 68 year old man, cares on a daily basis for a community of Sika deer living in a nature park on the outskirts of the city of Dalian, in China’s Liaoning province. He feeds and protects them with such care that he has caused the population of these animals, which were in danger of extinction a few decades ago, to grow exponentially. In this documentary we can take a closer look at his daily routine and contemplate how his passion and love for these animals has become practically his sole purpose and also, probably, his obsession.
