A good widow is crazy

Machiko is in mourning. She is an unlucky woman who lost her two husbands in sex-related accidents. This time her husband died of a stomach illness. Miya, a female fortune teller, talks to Machiko while she is standing by the pond and tells her she's having problem with men. She goes on to say that she can judge whether she meets her soul mate only by having sex...but is Machiko, who received a huge amount of insurance money, really in the hands of evil?
