Verdacht - Giwaku - Suspicion East Germany 1982

They don't come much more obscure than this; a Japanese movie called "Giwaku" (in English, 'Suspicion'), and an East German poster, under the title "Verdacht".A young Japanese wife with a dodgy history falls under suspicion of murder ?
Whodunnit ?
More importantly, is that a Nissan Cedric ?
