After a defeat in the presidential campaign, Theodore Roosevelt leaves for the Brazilian wilderness in search of his lost youth. Alongside his friend Farrel Nash, his son Kermit, and the then Brazilian Colonel Cândido Rondon, the ex-president of the U.S. also embarks on a trip through his memories, revisiting an important period in his life, when he occupied the White House.

Roosevelt delights in the scenery of the lush Chapadão and recalls his efforts to preserve the natural beauty of his own country.

Rondon shows his darker side and T.R. remembers the drastic decisions he had to make to save the country from economic chaos.

In the memories, controversial decisions and a thirst for victory cost T.R. more than a good friend. Returning to the wilderness, the two commanders' ideological differences conflict. Rondon puts the well-being of his men in front of his own. The return to civilization is close, but will the group get there before it's too late?
