橫掃全球40多個獎項，劇力萬鈞不容錯過之作。1980年，西班牙南端，一個荒蕪而將近被遺忘的小鎮，發生了一連串針對少女的兇殘謀殺案。少女被發現陳屍沼澤深處，死狀甚慘，死前明顯被殘暴虐待。兩名重案組探員被派往接手調查，由於兩人辦案手法南轅北轍，價值觀更完全不同，他們必須放下歧見，才有望成功破案，將這名橫行多年、威脅無數少女的變態殺手繩之於法。橫掃西班牙電影大獎，緊張懸疑，加上氣勢磅薄的攝影，遊走迂迴迷離的沼澤，格調堪比美劇《True Detective》，憾動觀眾心靈，大獲影評歡心。一不小心，泥足深陷。

In an almost forgotten town, brutal crimes against young girls bring two cops together in the Spanish deep South in 1980. Even though they both work for the homicide division, they have opposite values and ideologies. In order to solve the murder cases and arrest the brutal serial killer who has taken lives after lives away, these two cops must put aside their disapproval to each other’s style to hunt down the murderer before more lives are claimed. Highly atmospheric, this neo-noir mystery is visually striking and emotionally thrilling.
