On a quiet night, a massacre occurred in the Bachimen area of ​​Keelung.An Indonesian fisherman brutally killed three members of the Amis captain and his family. Tong Baoju, a public defender from the same tribe as the deceased, was forced to stand against his tribe and was ordered to defend the fisherman.

Tong Baoju led the court substitute Lian Jinping and Lina, an Indonesian caregiver who knew the suspect's dialect, to form a defense team. They went deep into the case layer by layer, and unexpectedly involved a collusion between government and businessmen.
