Katsumi Kawahara

Produced by Hitoshi Matsumoto, Documental pits ten comedians against each other. The objective is to make each other laugh in a closed room. Each contestant brings a one million yen participation fee. The last person to stay in the room without laughing wins. The winner is awarded a 10 million yen prize and bragging rights as the funniest comedian.

Eight of Japan's top comedians selected by Daigo, including M-1 finalists and King of Conte champions, must each write and direct a short film with just one rule: include a single, hilarious gag. In this unprecedented competition, skilled comedians have just "one shot" to prove their true talent.

Shigeo is released from prison and immediately beaten up by some old associates, which results in him losing his memory. Kasumi, who just by chance happens to be the manager of a band, takes him in and discovers his talent for singing.
