Young, marginally talented keyboardist Jon (Domhnall Gleeson) can't believe it when he's tendered an invitation to join his favorite band by the group's enigmatic frontman (Michael Fassbender), who's never seen without his trademark papier-mâché helmet. When his vigorous social media chronicling of the experience leads to a potential booking at South by Southwest, Jon's not ready for the pushback from his reclusive bandmates.
