A popular Monday drama series, in which Yasuko Sawaguchi plays as Maiko Sawamura, the leader of Tokyo Metropolitan Police Mobile Investigation Unit 2, who seriously performs her duties although she has experienced a tragedy in the past.
"216" is a radio call sign assigned to Maiko's unmarked patrol car.
This series describes incidents and complicated human relationships encountered by mobile investigators who are dedicated to the initial investigation of various cases such as injuries, robberies, and murders during their 24-hour duties.
Unlike detectives of Criminal Investigation Division 1, mobile investigators are constantly driving through the city – from their perspective, this pacey suspense drama reveals the truth in seemingly unrelated incidents that occur in parallel.
