Lufton manages to outsmart Riling and move his herd unimpeded, but Riling and his men cause the cattle to stampede and scatter back onto the reservation. It would take several days to gather the herd, more time than Lufton has before the deadline. Garry becomes disgusted when a young man is killed in the stampede, and he switches sides. Amy still does not trust him. She suspects Garry of betraying the contents of a letter to Riling, unaware that Carol is enamored with Riling and is the one passing information to him. Eventually, Amy comes to trust (and fall in love with) Garry, especially after he defends her father from two of Riling's men.
