This film is about a family of crooks who own a house somewhere outside a small town in the post-WWII United States. They have developed numerous ways to swindle money and goods out of various strangers who happen to stop by their house which looks like a regular country-side family motel. Be sure, they're real masters of this dangerous but profitable business. However, some serious misunderstandings and suspicions grow up between the family members, and here comes the final game with a nice twist at the end.
The actors really didn't have much to work with here, the plot hangs together like loose sand. If there would have been some interesting characters and dialogue or events you could maybe get over the fact that its just people getting conned for most of the movie rather than there being a good story or. Sadly, this is not the case. As a result none of the actors were able to ever rise above the level of stereotypes.
So in short not a bad idea for a movie, but it lacks too much of anything that can make a movie good. I definitely do not recommend it. Go watch the Sting if you're in the mood for this theme.
