Ped (Jirayu La-ongmanee) is a shy boy who never listened to music until would-be childhood crush Ern (Nattasha Nualjam) introduced him to the world of Pop and Rock. But she left for Bangkok soon after, and it's six years later, in their final school year, before she's reintroduced to Ped and his brash best friend Koong (Pachara Chirathivat). Koong convinces Ped, along with schoolmate Ex (Thawat Pornrattanaprasert), to form a band, partly to be cool and attract girls, partly so Koong can try to one-up his popular twin brother Kay. Their musical talents aren't great, but that doesn't stop them from trying. However, when Ern decides to lend them her outstanding guitar skills, Ped and Koong's shared attraction to her puts a strain on the band's survival, as well as their friendship.
