New travel writing assignments have brought Julia and Robin to Taipei. For her latest column, Julia decides to go against the tourism board's wishes and write about the betel nut girls - young scantily-clad women, selling this addictive treat on Taiwanese roadsides. Meanwhile, Robin discovers the creator of fire therapy - a risky form of traditional medicine for both patient and doctor alike. Feeling the burn, he joins Julia to flush out an article about Modern Toilet, a bizarre toilet themed restaurant.
