The Beast of Hollow Mountain

In southern Mexico at the turn of the 20th century, American cowboy Jimmy Ryan leads his business partner Felipe and their worker Manuel into the area known as Hollow Mountain in search of lost cattle. As they investigate, a series of mysterious events unfolds, including a young boy's near-death experience and a gang attack on Pancho, Don Pedro's son-in-law. Amidst these dangers, Jimmy finds himself drawn to Sarita, Don Pedro's daughter, who harbors feelings for him despite her engagement to the abrasive caballero Enrique. As tensions rise between Jimmy and Enrique, the true nature of the Hollow Mountain - a place where a dinosaur lurks in wait - threatens to tear the community apart, forcing Jimmy to confront his own destiny and the secrets of the mountain.
