Based on an actual event. A cash delivery truck is ambushed and robbed in a quiet highway. The perpetrators are neither gangsters nor habitual offenders. Instead they are good-hearted and law-abiding citizens. These five persons are rookie insurance salespersons who find it impossible to meet their quotas or get work elsewhere. Filmed in a sober style and featuring eyepopping deep-focus photography by Takeo Ito, Wolf depicts a period of deep recession following the end of the American occupation of Japan. Shindo's austere use of dialogue and music makes this film a far cry from the sentimentality of his previous films like Miniature or Ditch. Long stretches of wordless scenes make Wolf a foreshadow of the entirely wordless The Naked Island, made just 5 years after.
