Considered to be a witch, gypsy girl Tirza (Susan Harrison) has been condemned to death by her own tribe. Taking refuge on the Ponderosa, Tirza falls in love with Joe Cartwright, who is determined to prove to one and all that the girl is not the sorceress she appears to be. Cult film director Hugo Haas appears as tribal leader Zirka, with Arthur Batanides as Spiro and Lily Valenty as Bruja. Originally broadcast on April 23, 1960, "Dark Star" was written by Anthony Lawrence. ~ Hal Erickson, Rovi
