Jonathan Demme - Last Embrace (1979)

Synopsis:
When his wife is killed in a restaurant shoot-out, intelligence man Harry Hannan (Roy Scheider) has a breakdown and finds that his department doesn’t want him back. Someone’s trying to kill him and it could be them, though a cryptic Jewish death-threat suggests there’s something else going on. His only ally seems to be mousy Ellie Fabian (Janet Margolin) who has managed to move into his New York apartment.
