Simply put: Edo period playboy falls for women from ONE family that cursed his own and fails to evade the consequences.
It's quite unique, though I felt like something was missing. Overall it's not a bad movie, just wished the backstory had been explored more and explained in a longer sequence since it's the main plot point that drives the curse of Shinkichi's life.
I preferred the atmosphere over the horror aspect, too. There's not too many murders anyway, but they did the period-accurate environments and costumes really well
