Three single wives

When Anne Wilkes, Eliza Tate, and Penny Sands arrive at book club with author Marguerite Hill, none of them are plotting to kill anyone, or bury any bodies. They have a lot of wine; they discuss a lot of things. When the subject of a philandering husband arises, revenge is in the air. By the end of the night someone is dead. All three of the women are hiding something. All of them are lying. -- adapted from jacket and perusal of book
