The Texas chain saw massacre

The year is 1974. A group of 20-something college students are heading through the back roads of Texas en route to their grandfather's grave.

Among them are Sally Hardesty (Burns) and her brother Franklin. They encounter an unpleasant hitchhiker (Neal) who slashes both himself & Franklin with a wicked-looking knife.

The others manage to eject the hitchhiker from the vehicle, but shortly afterwards, they are forced to stop & wander over to a small, sinister clapboard house nearby. What none of them realize is that this house is the home of the ghoulish Leatherface (Hansen) and his evil, demented family of cannibalistic psychopaths. One at a time, the students are murdered for food by the evil Leatherface in horrifying ways. Sally soon finds herself an involuntary guest at Leatherface's home, and flees into the night to escape the demented cannibal and his loudly-buzzing chainsaw.

Can she escape the grim fate that befell her friends & brother?
