Bat has an interest in a mine in Colorado and discovers its conditions are unsafe, but the general manager is forcing the miners to work in it anyway. He decides to convince the other owners including its pretty namesake to improve safety.

When Bat catches his gambling casino partner embezzling money, he kicks the man out, telling him never return unless he brings $25,000 to buy Bat's interest in the business. The partner plans to get control of Bat's half by killing him.
