British doctor Richard Johnson arrives in the city of Bath, where a smallpox epidemic has broken out. If he has any hope of stemming the disease, he must locate and isolate its source. As if he hasn't got enough trouble on his hands, Johnson must contend with his failing marriage to Claire Bloom. Both of his problems are solved to everyone's satisfaction, but not without a few hypertense moments along the way. Director Val Guest lifts 80,000 Suspects out of the ordinary with his inventive utilization of darkness and shadows. ~ Hal Erickson, Rovi
