While on an undercover mission with Toshio to a secret hotel casino, allegedly operated by a mafia affiliate, Hitomi recognizes a painting from their father's art collection believed to be long lost. Hitomi accepts a challenge to a game of roulette on the condition of being awarded the painting "The Dangerous Woman". However, the owner of the casino is not willing to give up their most priced possession so easily; and for that, Hitomi - along with Toshio, who was captured while snooping - must travel to Guam to challenge the owner on their own ground.
