In London at the beginning of the twentieth century, Phyllis Allenby is a young and beautiful woman who is soon to be married to barrister and boyfriend Barry Lanfield.

Phyllis is living at the Allenby Mansion without the protection of a male, along with her aunt Martha and her cousin Carol and the servant Hannah.

As the wedding date approaches, London is shocked by a series of murders at the local park, where the victims are discovered with throats ripped out.

Phyllis becomes extremely terrified and anxious, since she is convinced that she is the "Wolf-Woman", deeply believing in the legend of the so-called "Curse of the Allenbys".

[8] From contemporary reviews, Thomas M. Pryor of The New York Times wrote that "this latest release from Universal's bottom-drawer [...] it certainly doesn't justify the effort expended in its behalf".

[9] A reviewer in Harrison's Reports found it "boresome and long-drawn out" with a plot that "has been done many times [...] there is nothing about either the action or the characters that is horrifying or terrifying".

[9] Jack D. Grant of The Hollywood Reporter gave the film a positive review, noting Yaborough's ability to generation suspicions and that "it was a difficult task to balance these strange acts by other characters at the same time maintain the mood of the period piece".

There is no "She-Wolf" in this quasi-horror opus, just a greedy old dame (Sara Haden) "gaslighting" poor, anemic June Lockhart in order to inherit the girl's fortune", while "Jean Yarborough and cameraman Maury Gertsman did their best to liven things up with odd camera angles and moody mise-en-scène, but all this was merely wasted on a typical Universal "B"".
