Quince and Mushy are returning from town when they hear what they think is a puma. Mushy wanders away and is knocked out by the cat and rescued by a stranger. The man tells them it is not a puma but an African lion he is hunting.
Favor hires Dan Carlock ('Forest Tucker'), who has a mutual hatred with an escaped circus lion, to kill the animal before it devours Favor's cattle. Carlock had been hunting the same lion for four years. The drovers begin to suspect that Carlock is more dangerous to them than the lion. For example, a drover who was wearing Carlock's shirt was killed by the lion. And they think the lion stampeded the herd in another attempt to kill Carlock. The drover's even convince Favor to fire him, but he tells Favor the personal reason for his hunting the lion, and so convinces Favor to let him stay on the hunt for one more night. Carlock has befriended lonely and ridiculed Mushy, who is thinking of leaving the drive. Everything comes to a head as Carlock recruits Mushy for the last night of hunting, gives Mushy his shirt to wear as bait, and waits for the lion to attack! Written by
