The real-life Yellowstone National Park provides a colorful backdrop to this melodramatic actioner. Henry Hunter stars as park ranger Dick Sherwood, who gets mixed up in a series of murders. The killings are tied in with $90,000 in stolen money, which the four villains had hidden in a Yellowstone cave 17 years earlier. Upon their release from prison, each of the criminals makes a dash for the dough; only three survive. While trying to figure out the murderer's modus operandi, ranger Sherwood takes time out to romance Ruth Foster (Judith Barrett), daughter of one of the crooks. Some of the violence in Yellowstone is quite startling, especially when the body of murder victim James Foster (Ralph Morgan) comes shooting out of "Old Faithful"!
