The title of this effervescent musical comedy translates as There is Only One Love. Louis Gravuerre and Heinz Ruhmann star respectively as an opera singer and ballet master, bosom buddies who embark upon a vacation in the Balkans. Thanks to a cluster of coincidences, our heroes are mistaken for escaped criminals and forced to take refuge in the remote mountain cabin of a taciturn hunter. Only when heroine Jenny Jugo identifies the boys are they permitted to go free -- only now, they can't get rid of Jugo, who has fallen madly in love with Gravuerre. The girl's well-meaning interference nearly causes an irreparable rift between the two pals and almost scuttles Gravuerre's singing career, but love triumphs over silliness in the finale.
