In this loose adaptation of Hamlet, illegitimate son Koichi Nishi (Toshiro Mifune) climbs to a high position within a Japanese corporation and marries the crippled daughter (Kyoko Kagawa) of company vice-president Iwabuchi (Masayuki Mori). At the reception, the wedding cake is a replica of their corporate headquarters, but an aspect of the design reminds the party of the hushed-up death of Nishi's father. It is then that Nishi unleashes his plan to avenge his father's death. In Japanese. Original title: Warui Yatsu Hodo Yoku Nemuru.
