Character Limit documents the changing fortunes of four citizens of the internet. They navigate a terrain of bloggers, vloggers, trolls, arseholes, attention-seekers and egotists that populate the virtual realm in which we all now spend half of our lives. We meet Jenny, a feminist vlogger who receives a misogynist backlash; Cameron, a straight ally who sets up a popular but mysterious campaign called #SaveSergei; and Natalie, a teenager who airs her dirty laundry online. And we also meet the people who are affected by the trio's actions online.
