Conan, Ran, Sonoko, and Masami walk through the woods to a villa where Masami's brother was called to investigate the mystery of the Red Woman, a person who 15 years ago had murdered her husband because he had an affair and is reputed to be haunting the area. They meet with a group of friends who have made an annual visit to the villa because their friend Satoko died 3 years ago after which they have found her dead body. They describe how every year they had experienced strange events related to the Red Woman such as a window breaking and a room with red apples, a water heater filled with red rose petals, and a big splotch of red paint on their door. While Conan and Sera investigate the Red Woman's appearances in the woods, Ran, Sonoko, and the rest of the group split off to do house chores. When Ran, Sonoko, and one of the women Masaie go to take a bath, they found Hakuya (one of the guys) dead in a bath full of tomatoes.
