"Jett" is the story of the rise and fall of a dysfunctional band in the seedy, bustling world of Melbourne's underground music scene. When Jett Walker (Adam Boswell) proposes starting a band with his friends Flynn, Drew, and Kitty, what starts off as a pursuit of passion quickly escalates. After a rocky start, fame lifts the ambitious young friends to new heights and "Heavy Lies the Crown" becomes a household name. As Jett embraces the rock-star lifestyle, egos begin to clash as relationships form and break, and as the music and the business come to odds. When tragedy strikes, the band's loyalty to the music - and to each other - is put to the test.
