Homer Bedloe, trouble-shooter for the C&F W Railroad, is sent by railroad president Norman P. Curtis to the little community of Hooterville to find out why a branch line doesn't connect with the main line. The branch line carries the "Cannonball" train, and is vital to the Shady Rest Hotel, run by Kate Bradley, her three grown daughters and "Uncle Joe" Carson. If Bedloe succeeds in shutting down the Cannonball, Kate faces ruin. John Ashley appears as passenger Fred.
