My Own Pal takes Tom Mix out of his customary western surroundings and plunks him in the middle of New York City. Joining a travelling rodeo, Tom O'Hara (Mix) and his beloved pinto Fritz are whisked off to the Big Apple, where he takes up residence in a theatrical boardinghouse. Here he renews his acquaintance with Alice Derring (Olive Borden), whose honor he had previously defended on the eastbound train. It so happens that Alice is the daughter of a New York police chief, thus she's able to enter Tom and Fritz in an upcoming police riding tournament, leading to a job on the force as a mounted officer. In this capacity, our hero captures a fleeing jewel thief by lassoing the miscreant's motorcycle. Barely pausing for breath, Tom spends the final reel rescuing Alice from her kidnappers.
