While the whole set-up of this RKO B-movie is ridiculous, the film is nonetheless worth watching.
Viewers of the recent thriller/horror movie "Identity" will quickly realize that the screenwriter of that flick has obviously seen this movie.
At just over an hour, the plot here is barely fleshed out, with one contrivance piled on top of another.
The performances are either ridiculous ("Doc" Joseph), or sincere (Anne Revere, Gale Storm). The location set is well-designed, being realistic, as opposed to a back lot imitation.
