Bill Bailey matches extraordinary NHS workers with some of the UK’s best artists. In this episode, Martin is taken on by Nick. Inner-city trauma surgeon Martin treats two stabbings a day and two shootings a week, and most of his patients are still children. But it’s his work outside the operating theatre that’s saving the most lives. Sculptor Nick Elphick aims not just to replicate the human form but to express a deeper meaning within his pieces. Will he be able to capture everything that Martin is?
