This film is based upon Gail Sheehy's pseudo-sociological book dealing with streetwalking prostitution in midtown New York, and features Lee Remick as a middle class magazine journalist who selects one particular harlot named Wanda (Jill Clayburgh) with whom she somewhat bonds in the course of investigating unsavoury real estate dealings involving socially prominent figures who ostensibly benefit from prostitution income. Despite the use of open mikes and harshly grained lighting to bring about a sense of aural and visual realism, the work suffers from a romantic approach to its subject, presenting the prostitutes and local police who arrest them as one reluctantly interlaced family, with the pimps grotesque caricatures, and the direction by Joseph Sargent vying with Jerry Fielding's jazzy score for being the most unimaginative contribution, whereas those real problems associated with this type of vice activity: venereal disease, the deleterious effect upon local business establishments, etc., are barely touched upon, indeed being submerged beneath a flurry of bootless subplots.
