Il Fiacre N. 13 is based on the novel of the same name by Xavier Montepin. The title translates as Cab No. 13, and the two-part story ("Il Castigo" and "Delitto") concerns the various amorous occupants of that cab. Several of the leading actors essay multiple roles to detail the intrigues arising from the many furtive glances, stolen kisses, and forbidden assignations. The film didn't do too well when first released in Italy but had better luck in South America. A French-language version of Il Fiacre N. 13 was lensed simultaneously, with some of the same cast members. ~ Hal Erickson, Rovi
