The first 4 vegans arrive in Merthyr Tydfil to spread their message, but although they have a shared goal it soon becomes clear that they take different approaches to the task. Local residents have mixed feelings about veganism.

The vegans are joined by body builder Korin who targets local gyms and a body building competition. Jodi makes progress with the local farmers at the town's market but then a vigil outside an abattoir backfires.

It is the final week for the vegans in Merthyr and they face their most ambitious project - a takeover of the local college. They set up a vegan BBQ at the farmers market.
