Pitfall

The film is set against the background of labour relations in the Japanese mining industry. The mine in the film is divided into two pits, the old one and the new one, each represented by a different trade union faction. A mysterious man in white, whose identity we never learn, murders an unemployed miner who bears an uncanny resemblance to the union leader at the old pit and bribes the only witness to frame the new pit. The two union leaders go to the murder scene to investigate only to come across the body of the witness, who has subsequently been killed. They blame one another and begin a fight which ends in both their deaths
