Based on a novel by Cornell Woolrich, Manhattan Love Song charts the misadventures of the madcap Stewart sisters, Jerry (Dixie Lee) and Carol (Helen Flint). Suddenly finding themselves broke, the girls are forced to become the servants of their former chauffeur Williams (Robert Armstrong) and maid Annette (Nydia Westman). This seemingly untenable situation ends happily when Jerry falls in love with Williams. Because of this Monogram production, Fox's movie version of Kathleen Norris' novel Manhattan Love Song had to be retitled Change of Heart.
