In an emotionally charged trial John Adams defends the British sentries involved in the Boston Massacre who contend they were provoked into firing on the assembled crowd. John's success brings him offers of positions in the Massachusetts government. But after John Hancock rouses a crowd to tar and feather a representative of the British East India Tea Company and the British respond to the growing unrest with oppressive measures, John instead speaks against the British policies and chooses to represent Massachusetts in the Continental Congress.
