一條狗的命運映射了一個人的一生，幼小的puppy被受雇的黑人毒打虐待，讓怨恨深深地植根于它的記憶中，于是成長過程中見了黑人就拼命撕咬，變成一只與黑人為敵勢不兩立的“white dog”，主人還自豪地宣稱著“the best of a lot”。最后，善良的女孩和馬戲團的人們一起施救，試圖挽救它，可能太著急了，救治節(jié)奏快了些，結果這只white dog went crazy and got shot due to attacking the old owner of the circus. It is sad that the poor dog experinced a poor life.
