A decade since his last campaign, 89-year-old former senator and 2008 presidential candidate Mike Gravel comes out of retirement when a group of teenagers convinces him to run for president one last time. Through the senator's official Twitter account, the "Gravel teens" embark on an unlikely adventure to qualify him for the Democratic debates in order to advance an anti-war, anti-corruption, and direct democracy agenda in the 2020 presidential race. Working together, the young activists and the experienced politician confuse and amaze the generations between them.
