At the beginning of his career, Armstrong made an instant impression upon the global cycling community, but it was generally agreed that, because he wasn’t suited to extreme altitudes, it was highly unlikely that he would ever win the Tour de France.

By 1998, however, Armstrong had come through a battle with testicular cancer and was determined to conquer the Tour at all costs. Employing a pharmaceutical regimen developed by Italian physician Michele Ferrari (Guillaume Canet), Armstrong put together a team of cyclists with a seemingly flawless strategy for winning — and for passing drug tests. While Armstrong’s colleagues applauded his inspiring feats, Walsh and The Sunday Times engendered formidable hostility and spurred litigation by posing the accusations that no one else wanted to hear.
