Charlotte and Denise Dunn own an audio company supporting concerts and conventions. They are pulled over by the sheriff in the middle of the night because their truck is overloaded and has worn tires. Of course, their truck is overloaded. It’s always overloaded, which is why they were passing through this small town in the middle of the night to avoid the weigh station on the Interstate.

At their arraignment, the sisters agree to stay in this town, buy tires, and lend their experience and equipment to support the harvest festival in place of fines or penalties. The sisters quickly realize that they have been set up. While the truck was overloaded and their tires were unsafe and should have been replaced long ago, their apprehension on these charges and the offer made to them was no accident.

The featured performer at the festival’s concert series was a young girl dying of cancer who had aspired to sing in a professional recording studio. The town’s community theater and the Dunn sisters’ equipment would fulfill the girl’s dream.

The sisters called their booking agent to inform him they would be unavailable until after the festival. Far from being upset at having one of his most reliable vendors conscripted in this manner, the agent saw this as an opportunity. He needed a rehearsal studio for a musical group about to embark on their first concert tour. He had worked in that theater long ago and knew the manager. The theater and the Dunn sisters could be the solution to several challenges he faced.

With less than a week to promote and execute a show, the agent drafted his granddaughters to help the festival. The girls dove into the new project with all the energy a teen can bring to bear on something they care about.

The agent rekindles an old flame. Charlotte’s ex-boyfriend shows up. Denise and a local mechanic with a young son find each other. Other romances happen.
