A Summer in a Sea Shell 1985 on netflix

Young Tomaž has many problems. Not only is he quite lonely, but he also has to leave his hometown and move to the city with his family because of his father’s new job. In these difficult times, his only help is his computer Vedi. Even disputes between local gangs can not solve any problems, at least not until both gangs get a common enemy – motorcyclists who steal shells.
