Sahara Takako is a lawyer who specialises in civil cases. She hates to lose and will use whatever means necessary to pursue the truth. Despite her competence, she is mocked as a rotten lawyer for defending companies that exploit their employees and winning many of these lawsuits. One day, Takako gets an unexpected request from a veteran lawyer, Harayama Masao. He would like her to take over the defence of a woman because he is in poor health and needs to be hospitalised. This woman is Shirakawa Kumako, who has been in the public eye. Called “Onikuma” by the public, which is a play on her maiden name, Onizuka, she faces charges of killing her husband Fukutaro, the owner of an established Atami restaurant, for insurance money.
