S1·E14 Man from the Sea

Twin sisters Judith (Carol Lynley) and Susan (Shirley Knight) Morrow, who are the daughters of a deceased friend of Judge Garth, come to Medicine Bow where Susan is to start a pottery. Also arriving on the same train is a sailor, Kevin Doyle (Tom Tryon) who wants to settle down and become a farmer. While Susan is more reserved and practical, Judith dreams of seeing exotic places and is captivated by Kevin's stories of travel to faraway lands. They begin seeing each other but Judith seems to act strangely. Kevin finds himself so in love with Judith that he agrees to give up his dreams of settling down and take her to the places she has always wanted to see...but her problems are such that this will never come to be.
