Twins Hinako and Minako (Mika and Rika Nakamura) haven't seen each other in 13 years -- and for good reason: They bring out the worst in each other. But when Minako discovers she's dying, she's determined to lay eyes on her sister one last time. Now, the girls -- and everyone around them -- are in grave danger as Hinako, a serial arsonist, and the secretive Minako display their combined psycho-pyromaniac tendencies in this Japanese thriller.
