For his final meeting of the day he shows up at the wrong address. It also happens to be in the worst part of town and the joint closes at 7pm. Then Martin gets hit with another unwelcome realization - the parking lot he left his rental car in closed up even earlier.
His wife shows up just in time to be stranded with him as the cab driver who brought her speeds off. The cabbie and seemingly everyone else in the movie knows the area to be bad news for every kind of reason. For the unlucky tourists it is something they will discover the hard way as locals of a malevolent intent detect their presence and elect to give them a hard time for ill-begotten fun and profit.
A cinematic cliché used far too often is the one where city dwellers get stranded in a rural setting and get brutalized by demented inbreds. The juxtaposition wherein small-town folks find horror in the big city is far more believable and I speak as a city dweller who dreads going certain places downtown. Numerous big North American cities are host to large critical masses of people on illegal drugs or off of necessary prescription drugs or both.
Eventually after a nightmare of an evening Marty comes to blame himself because it is accurate that he is at fault. Susan tells him the mistake he made was one anybody could have made. In the year in which this film was produced it might well have been a mistake anybody could have made. But we have cellphones now, Google maps, GPS etc now.
The suspense depicted here seems very real. Richard Thomas - long typecast as a wholesome farm-boy from his years on 'The Waltons' gave one of his better performances in this production.Not only are there solid performances by the leads but the supporting cast is particularly convincing. Michael Cavanaugh, Jordan Charney, Jeff Corey and Jonathan Goldsmith were always great.
