Go to my list →A criminal profiler in 2015 finds an old walkie-talkie and, to his shock, hears the voice of a detective in 1989. The two begin exchanging clues across time to solve unsolved cases and, if possible, change what happened to the victims. Each case raises the question of whether the past can truly be rewritten, and what it costs when it is.
