from 1950 come a neat thriller about a couple smuggle diamond from abroad and also the contagious disease smallpox . evelyn keyes pull out all stop a the essential victim of this film noir . once back in the united state she be not aware that she could be spread the disease on everyone and everything she come in contact with . eventually she be pursue and must be stop before an epidemic occurs . other than keyes strike performance there be good support from villainous charles korvin and william bishop and dorothy malone and lola albright and whit bissell . the finale be a humdinger with miss keyes on the ledge of a building with spotlight and hundred of spectator below . a good b flick .
