The story takes place in New York City, where Emily Eden is called to investigate the disappearance and murder of a Hasidic diamond jeweler. In order to find out who did it, Emily must go undercover in order to infiltrate the Hasidic community.
The movie was not advertised as a true-story movie, but according to Traciy Curry-Reyes, writer for the Movies Based On True Stories Archives/Database, it sounds similar to a New York murder case involving Chaskel Werzberger, 59, a Hasidic Rabbi, who was murdered in 1990. According to police, the killers intended to rob and kill another man who was a Hasidic diamond merchant, but that man was able to get away, according to the New York Times.
