Former rockstars’ stepdaughters, Liz and Mira, want to taste the wild sex life their stepdads, Jack and Mike, got in their youth. Dressed like groupies, they decide to follow a new rock band on tour with them to get some action. Jack and Mike don’t like the idea but don’t know how to stop their daughters besides grounding them. The girls figure out that if they can’t have sex with actual rockstars, then they’ll fool around with their stepdads’ old guitars. Unfortunately, their stepdads catch them in time and decide that if they can’t stop them, it’ll be safer to give them the wild sex they want themselves.
