Higashiyama plays the role of Umeki Ryusuke, a creative planner working in a IT company who happens to meet a mysterious beautiful woman Eto Miyuki and her male companion while returning from a drive as they try to hitch a ride from him. However, he finds out that the man died suddenly in a strange way while getting increasingly obsessed with Miyuki. When he realises later that the men around her die one after another under mysterious conditions, Umeki sets out to find the truth out of fear for his own safety.
As this will be the third time that Higashiyama is appearing in a Seicho work (the previous works were 1995's "Yakou no Kaidan" and 2004's "Shougen"), he felt that this drama had come at the right time given his current age. In the story, although Umeki and Miyuki aren't young people, their intense relationship is like a first love for both of them so Higashiyama described this as similar to "Romeo and Juliet".
