This plot, scheme reminds me something.... I don't know if you have seen BEYOND A REASONABLE DOUBT, from director Fritz Lang, or even John Sturges' THE MAN WHO DARED...Those two similar topics are not exactly the same as this one, but as twisted, daring f...up. The pure example of what B pictures are really worth for: unusual topics. I am not sure that this very story has been remade; I think it would be interesting to check it out, but you have to be lucky to find another film with the same plot. I won't spoil this move, an early picture from the future adventure movie specialist Lewis R Foster. I highly recommend it.
