Hired gun Silver (Peter Lee Lawrence) is a contract killer with style. He will kill a man for 1000 dollars, but he wouldn't quite take any job. He proudly says that he only kills people who deserve to die, he uses silver bullets, and he insists on being called 'Mr. Silver' not just 'Silver'. His paying customers include poor Mexican workers, who want him to get rid of their despotic boss, a sadistic landowner, or a saloon owner who needs him to kill a brutal bandit.
