Bette Davis and Margaret Lindsay portray stepsisters from a society family in this atmospheric tale of crime and punishment in the City by the Bay. One sister is amiable, upright, eager to uphold the family name. The other is volatile, risk-taking, a moth hovering too close to the flame of high-living lowlifes who launder stolen bonds. Care to guess which actress plays her? Bette Davis was a little more than three weeks away from the release of her breakthrough portrayal in Of Human Bondage and the excitement surrounding her was electric when she played the reckless sister in Fog over Frisco. That excitement flashes again and again in a trim, snappy gem Davis would later recall with much fondness.
