他的人生是黑白的。每天照料臥病在床的父親，當個無動於衷的社畜。但這個寡言憨厚的男人也很細膩，為植物澆水、餵食螞蟻、甚至會關注蜘蛛結網。父親去世後，他被迫搬家，碰上有史以來最熱的夏天。明明烈日當空、萬里無雲，天上竟飄來一朵雲，為他溫柔遮蔭。沒人相信他被雲纏上了，紛紛當他有病。雲兒哪管人間凡俗，它緊緊跟隨這個男人，時而像悲憫的天使，時而像鬧脾氣的情人，它是調皮的跟屁蟲，也是耐心的傾聽者。他愛上了這片雲。

Manik is a lonely middle-aged man who lives with his father, but with whom he has no contact. Instead, his life consists of taking care of his plants and ants, plus a spider and a lizard. But then a change happens in the man’s dull life – he notices a cloud in the sky that seems to follow him all the time. Life takes on a new, previously unknown value for him. Is it friendship or perhaps love?
