When Dora and Evie land at Windy's ranch in Montana, they're welcomed with a cattle stampede and a man from Windy's past. Sam, the love of Windy's life, has been framed for stealing a prized race horse, and Dora and Evie are obligated to stay and help solve the crime before heading back to Pensacola. 

With an entry into the Ms. Rockin' Rodeo pageant, a crash course in cow milking, and a stint as a rodeo clown, the crime-solving friends have their hands full this time. Can they prove Sam's innocence and finally get the evidence they need to return home to their beachside town and clear Dora's name?
