The Prague Orgy

When a famous American writer accepts a quest from a Czech emigrant to bring him back unique Yiddish manuscripts, he accepts not only a dangerous journey to Prague, where he is watched at every step he makes by communist secret police, but he also needs to face the emigrant's flamboyant and wild wife. She is in possession of the manuscripts and she is very angry at her husband, as he left her, with his mistress, for the US. She will not surrender the manuscripts easily.
