With the hair-trigger reactions of a former child soldier, Babeni Lenga dispatches the would-be date-rapist of Frederica Lane. Thus begin the murderous London adventures of serial killers Baba and Freddy. When newly mismatched partners DI Jackson Mendy (Babou Ceesay, Luther, Lewis) and DS Lola Franks (Eve Myles, Victoria, Broadchurch, Keeping Faith) join forces to catch the deadly duo, you'll cross your fingers for a quick thaw of polar opposites-somewhere between his irrepressible warmth and her self-protective chill. Hurry! Freddy's old boyfriends are a dying breed in this cat-and-mouse thriller from BBC Studios.
