Beloved teacher Miss Hinklefink inherits a western ranch, and to spend the summer with Professor Townley, she invites students Freddie, Dodie, Betty, Lee and Roy to join if Townley will co-chaperone. Sketchy real-estate agent Tom Sneed tries to persuade her to send the kids home when desperadoes rob the bank. Sneed's henchman mistakes Freddie for a baby-faced killer framed for a murder actually committed by Sneed, and ranch foreman Big Jim, also working for Sneed, tries to kill Freddie.
