In 2013, Jeff Bauman dutifully found a place near the finish line of the Boston Marathon to cheer on his girlfriend. And by the end of a day dedicated to running, he was no longer able to walk. Bauman’s story of survival is captured in the film “Stronger,” and he talks with us about living through one of the worst days in Boston history. We’ll also be joined by Jake Gyllenhaal, who plays Bauman in the film.
