The Trouper-Royale Orpheum Galaxie Theatre is a jewel in the entertainment crown of Niagara Falls. At least, that's what the marquee out front says. To the Fabulous Trouper Quintuplets their family's old theatre is a thorn in the crown of their adolescent memories. Under their famous-child-actor-turned-director father's overbearing, and narcissistic eye, the quintuplets are raised on a strict diet of Golden Age entertainment and homeschooling to mold them into the best actors of their generation. But through a series of hilarious and tragic events, the siblings begin to develop their own personalities and ambitions, rebelling against their father's aspirations for them. The tension rising from the quintuplets' newfound individualism sparks an onstage brawl during a performance on their 18th birthday that changes the trajectory of all their lives. Twenty years later, the quintuplets reunite for the reading of their father's will and his demand for one last performance.
