A fusion of film and theatre based on the play of the same title by Micomicon. The film shows the play and its creative process. After her mother's death, Antonia finds a box which takes her and her daughter on a trip through Europe to former Yugoslavia. Remembrance, exhumations and wars. Life will not be the same.

The routine is part of the life of all people, all to a greater or lesser extent are victims of this process. Although sometimes, sometimes things happen that upset her. Rubén starts his day like every day, he goes by bus every day and during the trip he observes the lives of all the passengers. Until one day when one of those passengers comes out of anonymity. He is captivated by her, every day he will see him at the same time in the same place, the number 15 bus. He wants to meet her but he is afraid to go near her, his friend Diego will help him or rather force him to overcome his fears.
