The documentary film "Valiant" is the powerful story of a desert-based ice hockey team that, in its very first year of existence, helps heal and unify its home city after a heartrending tragedy. The story opens with the creation of the Las Vegas Golden Knights – who defy the odds to make their home in the Mojave Desert as a National Hockey League expansion team. The team is enjoying pre-season success when Las Vegas experiences the worst mass shooting in U.S. history. On October 1, 2017 – just days before the Golden Knights’ home opener – 58 people are killed and nearly 500 others are wounded at the Route 91 Harvest Music Festival. In the face of this devastating loss, the Golden Knights – the only professional team in the city – makes it their mission to help unify and heal the community. This driving force takes them on an unprecedented streak to the Stanley Cup Final. Ultimately, the team wins gold by winning the hearts of the people.
