ABOUT THIS EPISODE When a 911 call goes wrong and a young man goes missing, it falls to Malcolm and Seong-Jae to investigate the responding officers when Internal Affairs' internal politics leave the case compromised and the officers aren't willing to talk. But with Seong-Jae on the wrong side of the thin blue line, tensions just may turn violent before the detectives find their answers—and only their trust in each other will keep this investigation from hitting a dead end. Will Malcolm and Seong-Jae's savage love survive the test, or will this case end in self-destruction? With Sade mysteriously vanished once more, taking one of their major assets out of commission, it's anyone's game. Especially when their missing young man becomes a dead young man … and no one will admit who's truly responsible for his violent demise. Contains mature themes.
