Warau Keikan plot
Asami Mizumura, a policewoman, is found dead in an apartment in Sapporo. Her ex-boyfriend, Sergeant Suguru Tsukui (Hiroyuki Miyasako), is immediately identified as the prime suspect. Tsukui is characterized as firearms dangerous and unstable and is ordered to fire immediately if seen. Koichi Saeki (Nao Omori) was once Tsukui's partner and has a strange feeling about the whole thing. He manages to contact Tsukui and hears from him that he has nothing to do with the case. While the entire police force searches for Tsukui, Saeki has only 24 hours to prove his innocence.
