It seems any kind of professional can be a detective in Japan. The latest vocation is tour bus guide, as exemplified by Sayaka Sakuraniwa (Hisako Manda) in the two-hour mystery "Yukemuri Bus Tour" ("Evening Smoke Bus Tour"; TBS, Mon., 9 p.m.).

Sayaka and her handsome driver, Ton-chan (Shingo Katsurayama) have been hired by newlyweds Shinichi and Tomoko Takanezawa to take them on a tour of Ise-Shima, where this summer's G-7 Summit is being held. The trip is a combination honeymoon and excursion, since both families are coming along. They stop off in Ige, where the Takanezawa family grave is, to pray for Shinichi's sister, Misaki.

Meanwhile, in Tokyo, police discover the body of a murdered man who they believe is the person whom murdered Misaki. The police detective goes to Ise-Shima to talk to the Takanezawas.
