It wasn't too difficult, but I figured out the plot and the ending within about the first 20 minutes or so. Not because I'm terribly clever, but because I've seen "The Prize", with Paul Newman, Elke Sommer and Edward G. Robinson, and also "The Lady Vanishes", a Hitchcock film from the 30's. Sadly, I'm sure the writer of this movie saw both of them as well, because the plot deviates only by time and circumstance, not the idea. It became less plausible as the movie progressed, leading to several "really?" moments near the end. Dislikeable characters abound in this poor, though contemporary version of earlier works that were just done better. Don't waste your time.
