Few people would have expected Utah to be a pivotal battleground in the fight to legalize same-sex marriage, thanks to the enormous public and political sway held by the Mormon Church. But in 2013 a brash gay activist and a small Salt Lake City law firm joined forces to combat Utah’s constitutional gay marriage ban, and what followed was a fascinating and improbable chapter in U.S. history. This award-winning documentary charts the state politics, Mormon influence, and behind-the-scenes setbacks that nearly derailed the lawsuit – as well as the impact it had on the national fight for marriage equality.
