Synopsis

This drama follows Hyakutake Makoto, a detective around forty years old living his “second life” as he races to uncover the truth behind an unsolved case from 10 years ago involving the mysterious death of the woman he loved.
 
The protagonist is Hyakutake Makoto, a detective at the Furuta Precinct of the Yamanashi Prefectural Police. So unremarkable to those around him, his colleagues have nicknamed him “Mob-san” – a joke at his expense meaning he blends into the background like a nameless extra. Ever since losing his beloved girlfriend Saeki Misaki in a tragic incident ten years ago, he has been sleepwalking through life in the shadows, watching his ambitious colleague Yoshioka Takashi forge ahead on the fast track to career success.
 
Then one fateful day, while closing in on a dangerous criminal, Makoto is shot — and when he regains consciousness, he finds himself back in 2016, ten years in the past. With full knowledge of everything that is yet to come, Hyakutake Makoto now races against time to protect the woman he loves and rewrite his own destiny, armed with a decade’s worth of first-hand experience.
