When a rather unusual van arrives in the village, the driver, a well-known rugby player, creates a real stir and it looks like the doctor's luck is changing for the better. However, Richard Sharpe, the mine manager, is furious and does his best to turn the locals against the doctor and his X-ray van - although his wife, Sylvia Sharpe, is rather taken with the new driver. Meanwhile, Gina gets some shocking news and the crucial green leather diary belonging to Dr. Elwyn goes missing.
