Convoy (1978)

A film based on a song doesn't exactly fill a viewer with confidence, but Convoy is a real gem; and thankfully it’s the kind of sharp-edged diamond that cuts, not the kind that buys you a wife.
Rubber Duck and his cohorts spend life on the open road, under blue skies, answerable to no one except the law. Unfortunately, sometimes the law is crooked and action needs to be taken to defend personal freedoms.
Replace the trucks with wagons and the diner with a saloon and you have the kind of Western situation where men are men and anyone not part of the clique is considered suspicious. Logic says the thin plot and recycled motivations shouldn't work, but somehow they do.
