It's that classic feud: mods versus rockers! As the boys get caught up in the allure of mod culture (the scooters! the hair! the fashion!), Shauna is testing her mettle as the queen of metal. But when the new King of the Mods is crowned, he sparks an all-out war between the musical factions, with the mystery team caught in the mix!
