Cast & Crew
Lassiter, a Texas ranger, is trapped in a remote valley with Jane Withersteen and little Fay Larkin when the huge boulder that he released to deter a group of pursuing Mormons blocks the valley's only exit. Twelve years later, Shefford, Lassiter's cousin, resolves to find his lost relative, but when the Mormons learn of Shefford's plan, they enter the "Secret Valley" and abduct Fay, who has grown into a beautiful young woman. The Mormon Elder Wagoner decides to make Fay one of his wives and imprisons her in the City of Sealed Wives, which later is raided by a United States marshal. Shefford rescues Fay and together they return to the valley, closely pursued by Wagoner and his men. Lassiter and Jane are about to leave the valley with Shefford and Fay when Wagoner attacks, but the four are saved by the marshal's men, who have been led to the valley by Shefford's loyal Indian friend. Shefford, who has fallen in love with Fay, is delighted to learn that she also loves him.
This was the sequel to Fox's Riders of the Purple Sage, released September 1, 1918 and also starring William Farnum and Mary Mersch. Exterior scenes were filmed in Arizona. Grey's novel was originally published serially under the title, "The Desert Crucible." It was remade twice by Fox: in 1925, with Tom Mix starring and Lynn Reynolds directing (see AFI Catalog of Feature Films, 1921-30; F2.4438); and in 1932, with George O'Brien starring and David Howard directing.
