Spin and Marty introduce the season and preview the events of their summer at the Triple R Ranch.

The gang's (mostly) back! Joe, Ambitious, Speckle, and Moochie are back for another summer at the Triple R Ranch. They meet Ollie's cousin Hank and await the arrival of Spin, Marty, and Perkins.

Spin, Marty, and Perkins arrive to the ranch in a fixed-up car. Unfortunately, it hardly survived the journey! Moochie sneaks in a surprise guest, and Perkins meets his new head chef (also named Sam). The morning following the first night's dinner and campfire songs, the White Stallion threatens trouble.

The camp is working on building houses for Moochie's rabbits when an emergency puts everyone on alert: the mares are missing! Annette visits the Triple R and introduces her friend Darlene to the boys.

Bill, Perkins, Spin, and Marty are after Dynamite; meanwhile Moochie has taken Chief and gone AWOL.
