While tumbling into a deep ravine (which, unaccountably, turns into a precipice), Clark Stuart (Ray Corrigan) manages to grab hold of a shrub and is eventually saved by the Rider (Julia Thayer) and her stallion. While Jim Bowie (Hal Taliaferio), Jamison (Hoot Gibson), and Davy Crockett (Jack Perrin) lead an attack against the enemy's mountain stronghold, Clark is literally working from the inside, having been shown the tunnel entrance to the hideout by the Rider. Unfortunately, the hero arrives just as Dupray (LeRoy Mason) and his men create another rockslide.
