Based on a popular stage musical comedy by Károly Bakonyi and Andor Gábor, the film tells the story of a young engineer who tries to construct a railway in his hometown, helped by the Count's daughter, Marcsa (Lili Berky).
It is a variation on the original legend of Alraune in which a Mad Scientist creates a beautiful but demonic child from the forced union between a woman and a Mandrake root. Not to be confused with the 1918 German version of Alraune.
