The series depicts the daily lives of creator/executive producer Polly Draper's sons who lead a fictional world-renowned rock band from New York City. As a mockumentary, the storyline is an embellishment of their real lives and the fictional presence of a camera is often acknowledged. Lead vocals and instrumentation are contributed by the siblings; they wrote the lyrics themselves. The show stars Nat Wolff and Alex Wolff, the lead singer-songwriter and drummer, respectively. Nat's fictional female admirer and real life friends--including the guitarist who had no prior acquaintance with the family--feature as the supporting band members, with the siblings' genuine father and Draper's husband as their according-playing dad and Draper's niece as the group's babysitter.
