The founders of the Saddle Club - Stevie Lake, Carole Hanson, and Lisa Atwood - are preparing for the adventure of a lifetime when their friend Kate Devine invites them to her family's ranch. They will have a whole week of riding with cowboy traditions, plus the fun of making Kate a member of the club. But when they arrive, the girls quickly realize that the West has more to offer than Hollywood scenes and colorful costumes. To show a cowboy that they are not just "silly cowgirls," they join in chores and help with a cattle roundup, where Stevie faces a dangerous venomous snake. Another bad news for Stevie: it's her birthday, and no one seems to care. However, she doesn't know that her friends from the Saddle Club have prepared a secret surprise!
