學齡前的阿毛與妹妹、好友阿寶無憂無慮地玩耍,三餐過得簡單而快樂。阿毛的爸爸曾隨國民黨來台,因被檢舉入獄,精神失常。媽媽為了維持生計,除了洗衣,還會以身體和肉販交換豬肉。阿毛每次看見媽媽換上碎花洋裝,去肉攤挑肉,他心裡充滿疑惑,直到某天偷窺到肉販車,聽見鄰居揶揄媽媽,他才明白「五花肉」的秘密。從此,阿毛不再吃五花肉,也開始厭惡媽媽的碎花裙。

Amao's mother exchanges her body for pork to feed the family. When Amao learns the truth, he began to hate his mother's floral dress — and refused to eat his once-favorite pork belly.
