America comes out of the closet in this exuberant musical based on real events. To the music of The Shangri-Las, Patti LaBelle and Judy Garland, Stonewall mixes outrageous lip-synching with glitter, romance and attitude. Small-town hustler Matty takes a Greyhound bus to Greenwich Village in New York City. There, he falls in love with Puerto Rican transvestite La Miranda, who introduces him to the Stonewall Inn, a popular gay bay owned by Skinny Vinnie.

It's the summer of love - but not if you're gay. The NYPD make regular raids on Stonewall, and Matty lands in jail. He gets another taste of police harassment on the night of June 27, but this time the enraged drag queens fight back. Leg by Vinnie's lover Bustonia, a riot breaks out which lasts for three days and sparks the birth of the Gay Rights movement.
