Seven deadly men ride into the quiet town of Genesis one day, a peaceful place that is growing and prospering. John Fontana is a strong and capable marshal and he's had no trouble preventing lawlessness until this strange group of seven men appears. They look like the worst kind of trouble -- even though one of them turns out to be Fontana's own brother. The deadly seven kill, rape, and plunder before riding out of town. The savagery of their violence quickly becomes legendary. There is only one way to stop them -- someone has to track them down and slaughter them one by one. Who will be more deadly? The men being pursued or the lawman relentlessly pursuing them?
