由1926年起，費爾南多波島（今稱比奧科島）隸屬西屬畿內亞。1778年起被西班牙殖民，比奧科島在1968年正式宣布獨立。然而不少殖民地的獨立過程都是不為人所道的，當中涉及權力的拉扯和潛藏的暴力，被歷史捨棄，被世人遺忘。電影故事正值於現今以及殖民地宣布獨立的大時代。多年來不穩的政局、權力的折磨、剝削的自由，都令現今的比奧科島的人民身心受創。兩個時代、兩種文化、兩代人民在電影中重新連結，女兒一次意外地發現父親的信件，講述年輕時在長期在島上生活點滴，故挑起她尋根的慾望。但重回出生地，一切又是否如期望中的美好？又或是重新攪拌深藏在歷史洪流中污衊的沙泥？

Since 1926 Fernando Poo’s island (Bioko now) was part of the Spanish Guinea and it has belonged to Spain since 1778. In 1968 was proclaimed the independence of the country. The increase in tension and violence of those years was a difficult episode in the island’s past that was not really well known in Spain. Palm Trees in the Snow places the action in the transitional period when colonies gained their independence and in the present, on Bioko, a wounded territory, affected by years of instability, dictatorships, disappearances, tortures and lack freedom. This story is as epic as intimate; it is a story that connects two periods, two cultures, and two generations. The unintended discovery of an old letter pushes Clarence to travel from the cold mountains of Huesca to Bioko to visit the land where her father Jacob and her uncle Killian spent most part of their youth, Fernando Poo’s island. In the depths of an exuberant and captivating territory, Clarence unearths the secret of a story of forbidden romance framed in turbulent historic circumstances whose consequences will reach the present.
