What Doesn't Kill You, the movie, reveals the true life drama that writer/director Brian Goodman underwent in his struggle to honor the people he loved – on both sides of the law. For two boys on the crime-filled streets of Boston's Southie neighborhood, a life on the wrong side of the law seems like a natural choice. But as the two childhood friends (played by Mark Ruffalo and Ethan Hawke) grow up, the stakes grow.
