Ibrahim came to Spain from Guinea Conakry and now his roots are in Madrid, where he lives with Mariama and works as a bricklayer. One day, the police arrest him and Ibrahim, who lacks a residence permit, is deported to his country. From that moment on, his only objective will be to return to Spain to reunite with Mariama and her daughter about to be born. After managing to cross Africa, he settles with some companions in Mount Gurugú, an immigrant camp that separates Africa from Europe. There he meets Aminata, a girl determined to jump the fence and reach Spain. But that is a physical feat that is not within everyone's reach.

In the borderless Europe of the 21st century, one border still separates Spain from France, marked by the Bidasoa River. On this river lies Pheasant Island, a tiny piece of land that alternates between Spain and France every six months. When the body of an illegal immigrant is discovered on the day of the border shift, Nassim, one of the survivors, becomes the target of a violent manhunt by French authorities as he tries to cross the border. This chilling event will change the lives of Laida and Sambou, an interracial couple.
