June Lockhart makes her first appearance as fearless lady physician Dr. Phyllis Thackeray. Paladin (Richard Boone) comes to Dr. Thackeray's aid when she insists upon treating, and sheltering, a pioneer family suspected of carrying typhoid fever. The assignment is complicated by the blind religious zealotry of wagon-train master Mulrooney (Grant Withers), who insists upon abandoned the stricken family in the middle of the wilderness--and Mulrooney has several men with guns to back him up. ~ Hal Erickson, Rovi
