A man is found stabbed in the back in his own yard, his wife was found by the police inside the house, covered on her husband's blood and prying. Annabeth watches Cindy Delacroix being interviewed and confessing to murdering her husband, when asked about the motive Cindy simply state that God told her to do it. Mrs. Delacroix's lawyer files a motion to declare her incompetent to stand trial. Officer Macklin asks Maureen if she can speed up the trial for one of his convictions, so he can have another solved case on his record, for a promotion he is applying, she promises to do whatever she can.
Mrs. Delacroix is submitted to a psychiatric evaluation and maintains her story about being commanded by God to kill her husband, even though she knew it is wrong. Cindy Delacroix is declared competent to stand trial, and has an outburst in the courthouse. She later gives an interview to a television channel, declaring she only did what God told her to do, and that the devil was in her husband.
Annabeth goes with Det. Mike Pitts to the Delacroix's home searching for a real motive for the murder, she asks the detective to check the family computer and finances. She then goes to their church and ask the pastor if there was any problems in the Delacroix's marriage and if Cindy ever gave any previous indication of being homicidal or anything like it. The pastor tells her how the Delacroix's were high school sweethearts and were together for a long time, but lately Barry had stopped attending church and how Cindy and Barry were growing apart. She inquires if he was gay, but the pastor refuses to answer.
The police find a dress in the Delacroix's home with a nametag with the name Marie on it, and wonder who she is. Annabeth asks Barry's brother about it and he reveals Barry developed a different taste in sex, but Cindy didn't approved it, so Barry decided to divorce her. In the computer the police find a lot of pornographic websites, and Barry's financial records show he spent a lot of money in some swing places. Meanwhile in Maureen's case, it seems like there is more to it than Officer Macklin told her and she gets suspicious. She confronts Macklin and he denies any involvement.
At the trial the defense tries to make it a religious battle, but Annabeth thinks there is another motive for the murder. Det. Pitts manages to find some of the swingers that knew Barry, and they reveal that Marie was in fact Cindy, and she came with him at all the swinger's event. One of the swingers testifies that not only Cindy participated in many of the swingers meeting, but enjoyed it too. Cindy starts screaming its all lies and demands to be heard, so the judge calls her to the stand.
She testifies the Lord told her to do whatever it takes to save her marriage and that's why she went with him to the swingier meetings, but she never enjoyed anything, she felt sickened by it all. Annabeth asks if she was ever forced or coerced by Barry to do any of those things, to which she replies no. Annabeth reveals to the court that even though Cindy did everything that her husband wanted her to do, he was going to leave her, and that's why she killed him. Cindy just explodes in rage and shouts she just didn't want Barry to leave her. After the closing arguments from both sides, Cindy Delacroix is found guilty.
