Mad Jack accidentally runs into Pinkerton, a man who wants to bring Adams back to the town for the trial. He rushes off to warn Adams, while that mountain is in danger when a volcano becomes active. While Jack tries to find Adams, Adams has to rescue the animals with Ben and Nakoma's help before the volcano erups.

Mad Jack meets a young tenderfoot named Teddy in the wilderness, and believes that he is just a clumsy novice, which turns out to be true, when Teddy, or let's say Theodore Roosevelt, attacks Nakoma & Ben and attempts to ride Number Seven.
