Three rogues (1968)

Two lone wolf yakuza (Hideki Takahashi and Kunie Tanaka) rob a gambling den, then split up when pursued by the angry gang. They eventually meet again at Tanaka's mother's rural farmhouse. By then, one-eyed Kobayashi has wrangled his way into the scenario, intending to get a split of the proceeds (since he had helped them get away). Although there is some dissension amongst the three, they eventually close ranks to fend off their stubborn, relentless pursuers. Unhappily, Tanaka’s mother (Chieko Naniwa) is killed in the process. There are also love interests (Yoshiko Machida and Kayo Matsuo) and some humor along the way. An admirably different approach to the formulaic ninkyo yakuza programmer, filmed largely in sweltering summer countryside locations.
