Syo and Han, colleagues, are out enjoying a relaxing day fishing, when they happen upon Mayumi and Misako, a very attractive young woman and her mother. Mayumi suddently faints, and the two men rush over to help. Her mother explains that she is very ill and only has months to live. Han invites them back to his place to rest. Mayumi and Han clearly are attracted to each other, and after a specific request from Misako, they sleep together. Things are about to take a turn from intriguing to weird, and even frightening, as Mayumi and her mother are not what they seem. A classic Pink love/horror story!
