Overview
Convicts on a chain gang sniff formaldehyde fumes to get high. They attempt a prison break and are shot down by the guards. After being buried, they rise from the dead, killing all in their path with shovels and hoes.

So a bunch of convicts on a chain gang snort some industrial scale formaldehyde before attempting a mass escape from their incarceration. They are all shot by their diligent guards and hastily buried. That it? Of course not, they all rise again and determine to avenge themselves on humanity. Perhaps more notable as a zombie movie because these are less robotic and monosyllabic - or had less starch in their corsets. Indeed one or two of them might have been half decent at Scrabble; but the end product is at least 15 years past it's see-by date and hysterical nonsense.
