This drama tells the story of the resigned police officer Dog Geshi (played by Yuna Hei), who suffers from absent-minded appearance but has an amazing memory. He partnered with the detective Arutoshi Arutoshi (played by Takahei Maruyama), who was transferred for the first time due to violence, but the first report rate, to challenge the bizarre case that has not been resolved for a long time.

The two build trust in the process of solving the mystery and face each other's trauma. It is a suspense drama that combines reasoning and human description.
