Leading Milan opera tenor Alessandro Zillani stars in the comic operetta Koengin der Liebe (Queen of Love). Zillani is cast as Mario Cavallini, a handsome singer who is zealously guarded from predatory females by his overprotective sister Angelina (Fita Benkhoff). When Angelina momentarily lets her guard down, Mario slips off to join a travelling theatrical troupe where he falls in love with aspiring songstress Jeanette (Carola Hoehn). The lovers conspire to dispose of Angelina by pairing her off with a comedy-relief composer (Rudolf Plaite). The leading characters over-act outrageously, as if worried that the audience won't realize that the film is supposed to be funny. ~ Hal Erickson, Rovi
