On the ocean liner he meets a "vampire" (Theda Bara) who is apparently notorious for seducing men with near hypnotic powers then sucking them dry of cash and driving them mad before moving onto the next victim. John shacks up with the "vampire", is he doomed?
So it's a bit daft though worth seeing as little of Theda Bara's work has survived, the original "vamp" girl had it all.
