Larry, who is awaiting a large inheritance, lives with his uncle who hopes to receive part of the hefty sum. He meets another specimen of its kind, weak, lazy and eager to show off, who lives on the hooks of an elderly woman. The two thugs sympathize and cause, by game, a fatal accident. From perverse games to silly games, they enter a deadly spiral.

A schoolteacher (Robert Dhéry) and his wife (Colette Brosset) use the couple's new car for a class field trip in this routine situation comedy. Soon the children are lost in this story written and directed by Jean L'Hôte taken from his own novel.

愚比王，又译作乌布王，是先锋戏剧家雅里创作戏剧，本片是在其过世后拍摄出来。《愚比王》以童稚般的天真和荒诞轰动一时，后续雅里又创作出《愚比龟》《愚比囚》，创立了啪嗒学，对后面的达达和荒诞派戏剧产生了一定影响。
