In one form of the Japanese tea ceremony, the host serves traditional kaiseki cuisine, sake and finally tea to the guests. The ritual, established as an art form more than 4 centuries ago, is believed to be the foundation of Japan's omotenashi hospitality. One woman has decided to embark on a unique nationwide pilgrimage to immerse herself in the art. Tsuruko Hanzawa is a rare "catering chef" of tea ceremonies. At 70, she loaded her pots, pans and tools for making tea onto a van and set off in her kimono, serving food using local ingredients and tea to the people she met along the way. Exploring a life devoted to tea, this documentary follows Tsuruko for 2 years as she battles illness to continue her pilgrimage.
