The movie looks at the story of David Walsh (Chris O'Dowd) and his long, torturous journey to expose Lance Armstrong (Ben Foster) and his use of performance enhancing drugs. 

Director Stephen Frears (Philomena, High Fidelity) has taken Walsh's book Seven Deadly Sins and put it on the big screen, following in the footsteps of two big documentaries about the cyclist in the form of Alex Gibney's The Armstrong Lie and Alex Holmes' Stop at Nothing: The Lance Armstrong Story.

This however, is a dramatised version of events, which picks up with Lance as his comeback is kicking into gear and he begins to win again after beating cancer. Although we only get fleeting glances, Foster looks the part so far, while O'Dowd's impassioned portrayal of Walsh looks like it could be great.
