A natty girl from the east, bearing the latest hints from Paris in her costume and get-up, arrives at the Diamond S Ranch and immediately becomes the cynosure of all eyes. Three cowpunchers of the wild and woolly order fall desperately in love with her in a minute. They are surprised to find that she is inordinately fond of athletics, and decide to go into training, sending to a mail-order house for a full lot of apparatus. They saw off their pants, make them into athletic costumes, and start madly into muscle-making on hickory horses, Indian clubs and other sweat producers. They meet with many mishaps, but grow strong and eliminate fat. After they think they are very fit, the athletic girl introduces them to a flat-chested, anemic-looking young man, and tells them he is to be her future husband. They sadly go out behind the bunkhouse, build a fire and resignedly consign their training outfits to the flames.
