In this film a UK couple travelling across Australia, pal up with an easy-going American who turns out to have a 'dark-side'.
This film scores in the respect that the way the American gradually reveals his hidden character is quite subtle. He manipulates the couple into turning against each other and then uses the chasm he creates to perform a divide-and-conquer type operation.
The film falls short in as much the female, as the easily duped girlfriend, isn't quite believable, and seems so gullible that if you told her with a cute smile that her panties were on fire she'd probably go and jump in a lake. Although I think this can be accounted for by the script.
Also the ending is quite silly.
