synopsis
Patricia Medina guest stars as Dr. Karen Miller, who has become an outcast on the frontier by virtue of her profession and her foreign birthplace. During a diptheria epidemic, Dr. Miller numbers among her patients another "outcast", namely ex-Army officer Jason McCord (Chuck Connors). As Jason struggles to recover from his illness, he decides to help Dr. Miller gain acceptance from the hostile settlers by acting as guinea pig for a new, untested serum.
