The sheriffs are called out to investigate cattle rustling at the McKay Ranch, so Yabba and Dusty go disguised as a lady bull and Scrappy as a cactus, to catch the thieves.
Scrappy-Doo is visiting his uncle Yabba-Doo and hoping to learn the ways of the west. A call comes in about cattle rustling at the McKay Ranch. On the way, Yabba suggests the old deputy disguise trick. Deputy Dusty says he's the leader and he should make the plan -- so he'll use the old deputy disguise trick. They disguise themselves as a cow (Yabba in front, and Dusty in back). Scrappy is disguised as a small cactus.
Soon a bull notices them and makes amorous advances. The fake cow backs up, gets pricked by the stickers in Scrappy's disguise, and leaps into the bull's arms. Then a rustler lassos the fake cow from a helicopter, flying it away from the unhappy bull. Scrappy chases after the rustler, still in his cactus disguise.
The first rustler, Jink, gets yelled at by his Chief for bringing in an unhealthy-looking cow. They drop it from the helicopter into a mud puddle, and the disguise comes off Dusty and Yabba. The Chief acts threatening, and timid Deputy Dusty tries to back off. Meanwhile, Yabba and Scrappy get up on a rock above the rustler and try to lasso him. Instead, they lasso Dusty and themselves into a big ball of rope.
The rustlers lock the three law-enforcers into a wooden shed. Jink flies back and gets the bull. When Yabba sees the bull he has an idea. He puts on the cow disguise mask. When the bull rushes over for a kiss, Yabba feeds him a super-spicy Chili Snack. The bull is so excited by this that he gives the shack a kick with his hind legs. The boards of the shack fly up into the air and rebuild themselves around the two rustlers, trapping them.
With everything under control, Deputy Dusty claims credit for his great disguise idea, putting on the cow mask. The bull chases him, and he runs, yelling for help. Scrappy and Yabba wink at each other, letting the Deputy take his medicine.
