Twenty-years after Star Trek creator Gene Roddenberry's death, his son Eugene "Rod" Rodenberry examines the cultural and philosophical impact of the visionary science fiction franchise. Eugene was just 17-year-old when his influential father passed away. At the time he couldn't quite grasp the influence that the imaginative, unapologetically optimistic series had on generations of fans. As Eugene matured, however, his appreciation for Star Trek began to deepen. In this documentary, Eugene speaks not only with the writers and actors who helped to bring his father's unique vision to the screen, but with other well-known producers, performers, artists and fans who have drawn inspiration from Star Trek over the decades.
