Based on a true story: in 1948, customs officer Mehdi has to formally set up the border between Turkey and Syria right through his home town. He is unaware of the pain he is about to create as families, languages, cultures and lovers clash and are ripped apart in a nation which feels as ONE. Furthermore, the new border also leads to the separation of Mehdi from his best friend Rahim who is the most important man in town: the only doctor.
