The Last Republican shines a light on a pivotal moment in recent history through the eyes of former politician Adam Kinzinger. As one of the few Republicans willing to break ranks after the 2020 election, Kinzinger knew speaking out could spell the end of his career. But with democracy itself feeling fragile, looking the other way wasn’t an option.

The documentary details Kinzinger’s final months in office. By then, he’d already drawn ire from his party for voting to impeach Donald Trump over the January 6th attack. When asked to join the committee investigating the insurrection, Kinzinger took the unpopular step of cooperating—not because he wanted to, but because our system of government was at stake.

Delving deep into this conscience-driven choice is director Steve Pink. An unlikely pair at first glance, Pink the liberal and Kinzinger the conservative find common ground in their concern for America’s future.
