Private eye Tajima (Suzuki perennial Jo Shishido), who runs Detective Bureau 2-3 with two eccentric assistants, persuades the police to let him infiltrate a yakuza gang in order to investigate illegal arms sales by GIs. He follows a trail that leads from girls in American-style nightclubs to men in high places before his cover is blown and a hit is out on him. This expert gangster movie-shot, as critics have noted, with a kinetic energy to make Sam Fuller weep-is also a set-up for Suzuki, the very type of film he will soon begin to parody mercilessly. Already, this is a stylishly idiosyncratic crime film; the sleaze factor is to die for.
