Who Killed Cock Robin

Nine years ago a hit-and-run left one witness who saw it and one survivor who lived through it, and no one was ever held to account. Wang Yi-Chi (Kaiser Chuang), a journalist, reopens the case when fresh clues surface, only to find the survivor has suddenly disappeared. Cheng Wei-hao sends him racing the clock through a system that doesn't want the old accident looked at, and Wang keeps digging.
