Out hunting stray horses, Bill and Calamity come upon a half-dead Indian afoot in the desert, ranting in native tongue about either a "ghost horse," or "bad monster horse," that is chasing him. It turns out to be a camel with her calf. Bill ropes the camel, and takes it in tow to The Judge's ranch. Sundown is nigh, but they won't take the short-cut through Sycamore Basin, for fear the camel may spook a stampede of the judge's new herd of Texas longhorns grazing there. An expository caption explains the presence of camels out west: imported by the Cavalry for desert Indian wars, wandering strays spooked horses and cattle for two generations. Meanwhile, the Conger Gang (rustlers) subdue the judge's three cowhands watching herd over the longhorns, and begin driving the herd from the Basin. The herd and the rustlers' horses catch scent of the camel, and go wild. Rustlers are thrown from their mounts. The longhorn herd stampedes. Bill and Calamity stand by the camel, and the cattle stampede parts to avoid the camel scent. Bill and Calamity subdue two rustlers, and Calamity takes them into town. Bill subdues two more rustlers, frees the three cowhands, and brings them all back to the Judge, who scoffs at the tale of camels. A rustler breaks free outside and gets Bill's gun... but the startled camel breaks its bonds, knocking down the two escaping rustlers and making the judge a believer. The Cavalry then comes for its camels
