frontier
A frontier is the political and geographical area near or beyond a boundary. The term came from French in the 15th century, with the meaning "borderland"—the region of a country that fronts on another country (see also marches).
A frontier can also be referred to as a "front". A difference has also been established in academic scholarship between Frontier and Border, the latter denoting a fixed, rigid and clear-cut form of state boundary.
I really enjoyed Triple Frontier and it's expensive cast, but surprised to see a sequel announced. Charlie Hunnam produces. Early days yet, but it'll be interesting as to who returns...
