George and Martha Thornton are travelling back home after visiting "Old Mexico". Martha sees a cactus, and insists George pull over so she can take a cutting from it to grow her own. George thinks it's crazy, but he allows it. The cactus grows well in their garden, as does George's hatred and fear for it. One night, he attempts to chop it up with an axe. To his surprise, the cactus takes the axe from him. Naturally, George screams in terror and runs away. The cactus shows it's prowess with gardening implements by deftly throwing the axe into the back of George's skull.
