Willie organizes a road trip to take John Luke and Mary Kate to Liberty University for their first semester. Korie, Sadie, Jase, Missy, and Si come along for the ride. During a visit with Willie's friend Colt Ford in Nashville, Si drives the family crazy with his dreams of being a rock star. A housing assignment mix-up leaves John Luke and Mary Kate without a place to stay until their house is ready, so Willie leaves the Duck Commander RV with them. As the family flies home, they stop in Nashville again so Si can indulge his performing fantasy onstage with Colt. To celebrate River's seventh birthday, Jep and Jessica help him film and star in a superhero movie. Phil, Miss Kay, Martin, and Godwin end up being dragged into Jep's grandiose artistic vision, which slowly deteriorates into egotism and utter chaos.
