An'gel and Dickce Ducote tend to stay put in Athena, Mississippi, but a wedding is a good reason to say a temporary farewell to Charlie Harris's cat Diesel and go visit relatives. But while their stay in Louisiana is scorching hot, the atmosphere at the wedding is downright cold, with bride-to-be Sondra Delevan putting her trust fund above little things like love and loyalty.

When a violent storm supposedly sweeps Sondra off a balcony to her death, the sisters discover that many of the guests attending the wedding had major reasons to object to Sondra's marriage. Now, it's up to An'gel and Dickce to use their down-home instincts to expose dubious alibis, silver-plated secrets, and one relentless murderer who lives for "till death do us part."
