Will Packham is an idealistic pupil barrister - or idealistic for now. His clients are at least as guilty as sin. His pupil-master Caroline thinks he is a gutless snowflake. His fellow pupils want the same job as him and would stab each other to get it. Over the course of two days, Will has to defend a would-be murderer, keep a young slam poet out of custody and fetch Caroline a range of pastries. Can Will hold onto his principles and prove he has what it takes?
