In the spring of 1987, an undeniable front runner emerged in the race for the Democratic Party’s Presidential nomination: Colorado Senator Gary Hart – whose smarts and charismatic idealism seemed all but destined for the White House and the making of a new chapter in American history.

By April, Hart had opened up a gaping lead in the polls. Three weeks later, in a spectacularly public fall from grace, he was out of the race and Presidential politics forever.

Drawn from Matt Bai’s book, All The Truth Is Out, the film zeroes in on those very last few days in which Hart’s promise and Presidential hopes fell apart.
