Viewed as historical fiction -- historical fact -- a study of various human isolation scenarios -- or merely an ensemble's exercise in character development, this is an unstinting work of fairly extreme realism that will miss most viewers but should be required for film students and anyone who aspires to credibly review movies.
Opinions differ but there is discussion that this scenario pays homage to an installation of soldiers in some way voluntarily burying themselves inside tunnels on the Rock of Gibraltar - can't confirm that.
There are many other works that present prolonged or profound human isolation in more contexts than I know of -- Apollo 13 comes to mind, among others.
I choose to think that this represents a real story. It is a terrific story in any case with minor perforations due to the cinematic medium.
