Maura is arrested after her date at a charity event turns up dead. She has no memory of the date until she gets roughed up in jail by a woman who thought Maura was responsible for her arrest. Maura remembers her date blowing a hallucinogen at her, putting her in a trance. Because her guard has ties to Paddy Doyle, she is allowed to use the jail's computers to help find the real killer.
