It’s the final week for the five vegans in Merthyr Tydfil. Jodi comes up with a new plan to spread the plant-based message by enlisting fellow Welsh vegan and local hero, Dirty Vegan Matt Pritchard. The group secure a pitch at the farmers market, where Merthyr residents sample vegan hot dogs and the vegans set up a toy dog on a BBQ, complete with fake blood. Meanwhile, Joey is challenged to assess his approach after spending time with a mother-of-two who is looking for nutritious and affordable meals for the whole family. As the three weeks draw to a close, what kind of impact have the vegans had on the community of Merthyr, and what have they learnt from the meat-eating locals?
