Lisa Ross arrives in the emergency room suffering from a serious case of cloracne, and suspicion immediately falls on her husband Greg, a prominent dentist, especially after her sudden death. As Goren and Eames dig deeper, they uncover rumors of Lisa's unfaithfulness, but a significant lead emerges when they realize she’s not the first woman linked to Greg who has died from similar symptoms. Their investigation reveals a connection between Lisa and Greg's former fiancée, Morgan Dexler, leading Goren and Eames to believe they are on the right track, though they still have more work to do.
