(くたばれ愚連隊, Kutabare gurentai, aka Fighting Delinquents) is a 1960 Japanese film directed by Seijun Suzuki for the Nikkatsu Corporation.

[1][2] Sadao, a young construction worker, believes himself to be an orphan and in spite of his youthful tempestuousness he is nonetheless a model of honesty and moral integrity: he introduces himself by crashing into the office of a company president in order to claim the indemnity that he owes the foreman's daughter because he caused the man's death by dangerous driving.

Shortly after this altercation, Sadao learns that he actually is the only heir of a noble and rich family from Awaji Island.

When the messenger realizes that the young man is immune to the material temptations such an offer carries, he manages to persuade him with the promise that he will be reunited with his mother.

The obaasan ("granny", as he defiantly calls her) is shocked by her grandson's disarming sincerity, a far cry from the hypocritical manners inherent in any high society member.
