Behind President Joe Biden's fateful decision are decades of challenges and controversies, triumphs and tragedies. FRONTLINE tells the inside story of Biden's rise to the presidency, and the personal and political forces that shaped him and led to his dramatic decision to step aside.

FRONTLINE investigates the lives and characters of Kamala Harris and Donald Trump as they seek the presidency. In a historic election, those who know the candidates best reveal key moments that shape how they would lead America.

Award-winning filmmaker Michael Kirk and his team, who have made five prior installments of The Choice over the past 25 years, sat down with Trump and Harris' friends, advisors, and critics, as well as authors, journalists, and political insiders to present deeply reported narrative arcs of both candidates' lives, going all the way back to their childhoods.

What emerges in The Choice 2024: Harris vs. Trump is the story of two fighters: One seeking vindication and promising a return to greatness, and the other seeking to move beyond the past and promising a greater future.
