It's the fifth game of the World Series, with the Phillies ahead of the Red Sox. The Phillies are ahead, but the Red Sox batter hits a home run.... and drops dead at first base, shot with a poisoned bullet. Who shot him? Why? How did no one notice?
Even more confusing to me is that these are Japanese teams playing in Japan. Oh, well. Baseball was enormously popular in Japan, and Sadatsugu Matsuda's movie is a fine melodrama, which seems to have its roots in the Black Sox scandal, and involves a mysterious mastermind and a denouement in a sawmill, out of good, old-fashioned melodrama. It's not a great movie by any means, but Matsuda was a prolific director, with 84 features from 1928 through 1969. Few of them were particularly distinguished, but when you're doing samurai movies and melodramas, you can have a handsome career, and there are some excellent sequences in tis one.
