Eighteen months and one day is how long Sabina Lamer, a famous painter based in Peñíscola, has been locked up in the attic where she lives. She suffers from severe agoraphobia, the result of the post-traumatic stress disorder she developed after being the only witness to the murder of her best friend, in the middle of the street, at the hands of her ex-husband.
Since then, Sabina has been unable to cross the threshold of the door of her house, which is also her studio, from where she looks out over the sea and the streets of the old town of Peñíscola, the city she chose to develop her professional career. She is convinced that when her friend’s murderer, who is in provisional prison awaiting trial, is locked up for good, she will be able to overcome her anguish and finally leave the house to paint the Mediterranean Sea she loves so much and return to her peaceful life in that paradise on the Mediterranean coast.
However, the presumed murderer is released and Sabina goes even more mad within the four walls of her studio. From that moment on, Sabina’s obsessive and recurrent idea is to seek justice, helpless as she feels by the judicial system, looking for a way to avenge the death of her friend, with the added difficulty of not being able to leave her home. To achieve this, she will have to confront herself, her fears, and the constraints of her confinement, turning her claustrophobic life into a means of escaping from herself.
