Nostalghia (1983)

Lushly beautiful and haunting, Andrei Tarkovsky's Nostalgia is also a challenging, thought-provoking meditation on man's search for self. Tarkovsky's film follows a musicologist, Gortchakov, during a research trip to Italy where the composer he's studying lived for several years. Gortchakov is apparently oblivious to his beautiful translator and the wonders of Italy, instead dwelling on memories of Russia. Things start to change when he encounters Domenico, a somewhat unstable man who has kept his family locked up for seven years while waiting the end of the world. Domenico has now decided that rather than wait he should do something about the end; and he's decided Gortchakov should help.
