Sawagura Nobuko is back housekeeping again in this sequel to the 2014 SP! This time around Nobuko, having been given some pearl earrings as a present sometime before, decides to attend an exhibition for a pearl described as being the world's most expensive one. That pearl is owned by the Iwakura family, who run a large pearl company. While looking at the pearl however, Nobuko is pulled away by a handsome man who seems to have some connection to the family. So when Nobuko finds one of her pearl earrings missing and probably taken by that man, she decides to work as a housekeeper for the Iwakura family until the man shows up again and she can get her earring back. But the Iwakura family that Nobuko is now working for has plenty of secrets beyond just pearls that she'll have to sort out if she wants her earring back...

The Housekeeper Saw!

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.
