Plot

In the chaos of 1968, a young up-and-coming band has to choose between fame or faith in this funky musical drama fashioned after late-60s pop culture- from The Monkees to H.R. Pufinstuf to A Hard Day's Night.

The Windies is a young up-and-coming band, trying to make it in a pop culture variation of 1968. Lead singer Flower Moon is depressed and on drugs, along with other members of the band, until a chance encounter leads them to a Christian coffee house, frequented by a group of funky ex-hippies. Flower and her bandmates Judy, Joey, and Boomerang radically receive Christ when the coffee house group prays for them (although it is dubious as to whether or not Judy is sincere or just going along).

A parallel storyline is unfolding on a psychedelic Pufnstuf-like television show called Captain Rumblepuff, where butterfly hostesses Cherry, Raspberry, and Soda Pop are trying to escape the monsters from Big Bad Island, only to discover it is their job to stay on the island and rescue other butterflies. Their story seems to mirror the story of Flower and the band, as well as the Gospel's Great Commission of "going into all the world to preach the Gospel to every creature".

Word gets out of the band's conversion, which doesn't sit well with the band's manager Al Deuce, who is intensely hostile to the band's newfound faith, eventually resulting in Flower quitting the band and breaking their contract with the recording label.

Judy reprimands Flower for ruining their chances of success, revealing that she never really converted. Though the rest of the band is determined to start again as a Christian band, still a strange but emerging idea within the Christian community, Judy has been more or less kicked out of the band after her argument with Flower. But her own convictions, coupled with the encouragement from two diehard Windies fans who have been greatly influenced by the band's conversion, Judy accepts Christ for real.

The band reforms as the Redeemer Band, and a newspaper article later reveals that the band has lasted for thirty years and was a pioneer of the contemporary Christian music genre during the "Jesus Movement".
