What's the Story?
In SIGNAL, a child is taken from a school, prompting a hunt for her killer that inspires Park Hae-Yeong (Lee Je-Hoon, Move to Heaven) to pursue a career in detective work. When a cold case from 1989 resurfaces, Park Hae-Yeong is teamed up with Cha Soo-Hyeon (Kim Hye-Soo), a female detective whose leadership skills have been hard won. One night, Park Hae-Yeong hears a noise from the evidence collection from the 1989 cold case. It's a walkie talkie; who's on the other end?
Is It Any Good?
Riveting and emotional with a moral center, this cold-case Korean thriller is driven by great acting. Signal doesn't woo with high-dollar effects; rather, its strength is the depiction of ordinary people who try to right the wrongs of some sickos doing harm. Throw in a metaphysical phenomenon, and you've got a winner.
Families who like cold-case stories will enjoy this one together. There are brutal images and themes, but they don't dominate as much as in other shows. The unanswered questions in this show will keep viewers guessing.
