The film blends reality and cinematic invention to chronicle the events surrounding the bombing that happened at the finish line of the Boston race on April 15, 2013. Investigators eventually narrowed down suspects Tamerlan and Dzhokhar Tsarnaev, and a huge manhunt followed, with Tamerlan killed in a firefight with officers and Dzhokhar found guilty of all his charges and sentenced to death.
Peter Berg and Mark seems like a solid team.
