Innocence forever unprovable!!!! The reversal of the case

Kikuchi (Itao Itsuji), a leading researcher on natural energy, is arrested for indecent assault. He allegedly touched Ihara (Fumie Hamakawa), a former colleague with whom he had been drinking, but Kikuchi has no memory of the incident. When Fukayama (Matsumoto Jun), who is in charge of Kikuchi, and others verify the story, they find discrepancies in Ihara's statements. The possibility of acquittal increases, but Kikuchi suddenly demands a settlement.
