S1, E5: Jiyoung, a young ice cream master, is found frozen to death in the freezer of the ice cream factory where she works. While Chris investigates the victim's stormy working relationship, Charlie tries to find out who Jiyoung was and discovers that the crime scene was an impromptu cryotherapy session gone wrong. The investigation eventually reveals that Jiyoung was having an extramarital affair with Vincent, the factory manager, who moves to the top of Chris's list of suspects. Charlie is left in the lurch by Samy, who has had a hard time of it with Charlie since their return from London, and is unable to convince Chris of Vincent's innocence. She needs all her energy to get to the bottom of the matter and reconcile with Samy. The two of them arrive just in time to prevent the real culprit, none other than Vincent's daughter, from committing the irreparable act. The latter will eventually confess: after discovering Jiyoung's affair with her father and seeing her family destroyed, she took advantage of one of her cryotherapy sessions to lock Jiyoung in the freezer.
