Robin visits universities in Hong Kong, Oxford and Washington to establish how important free speech is to them and whether moves to block controversial speakers is compatible with what appears a fundamental freedom of expression in places where all ideas are encouraged and tested. Robin explores where the line is drawn regarding freedom of speech in universities, who draws it and what happens to those who cross it.
