清晨的第一缕阳光照在碧绿的草原上，雄鸡对日长鸣，农场此起彼伏传来家畜的叫声。随着镜头拉远，我们看见这片灿烂光明的三维世界竟然藏在一个二维精灵的体内。他似乎是昼之精灵，他与白天融为一体。迈着轻快的步伐，昼之精灵四处游走，突然看见一个呼呼大睡的家伙。那也是一个二维精灵，其身体里是安静祥和的三维黑夜世界，小羊羔正一只只从围栏处越过。显而易见，这是夜之精灵，他不幸被充满好奇的昼之精灵吵醒，两个小家伙你追我赶，自以为是，互较高下，不肯服输。但在一连串的较量中，他们也似乎发现了对方的优点以及和自己的共通之处…… 　　本片荣获2011年安尼奖最佳动画短片奖、2011年视觉效果工会奖杰出视效短片奖。When Day, a sunny fellow, encounters Night, a stranger of distinctly darker moods, sparks fly! Day and Night are frightened and suspicious of each other at first, and quickly get off on the wrong foot. But as they discover each other's unique qualities--and come to realize that each of them offers a different window onto the same world-the friendship helps both to gain a new perspective.
