Brink of Life (1958)

While vacationing on a remote German island with his pregnant wife, an artist has an emotional breakdown while confronting his repressed desires.

Traveling through an unnamed European country on the brink of war, sickly, intellectual Ester, her sister Anna and Anna's young son, Johan, check into a near-empty hotel. A basic inability to communicate among the three seems only to worsen during their stay. Anna provokes her sister by enjoying a dalliance with a local man, while the boy, left to himself, has a series of enigmatic encounters that heighten the growing air of isolation.
